The Sinkhole 

He or she is either a friend or a relative.
That is all the sentimental value that you can sincerely attach to him or her. 
This person has always been in one form of trouble or another since you knew him or her.
 When you got close to him or her, you found yourself in major trouble, and as long as you remained friends with the person, you noticed you got distracted and started going into vices or getting pushed into doing things that you would naturally not do.
 Simply by being in the same circle as him or her, you find yourself meeting certain kinds of unscrupulous elements that you have no problem meeting.
 You find yourself trying out some illegal things for the first time. Using a Fake ID, trying out cannabis, smoking a cigarette, gate-crashing parties you have no business attending, meeting strange men, sleeping with strange men, doing drugs, sneaking out of the house to spend the night at one ungodly place or the other, getting arrested by the police, almost failing your exams, rebelling against your parents, skipping lectures, skipping church, engaging in petty theft, lying, setting a someone up for a sound beating, joy riding, seeing a weapon in close proximity for the first time, gambling, spending money that is not yours to spend and so on. It could be all or some of the things listed above, but you get my point; this person is a very bad influence. Your entire instinct when you are around this person is on edge due to a sense of constant danger and adventure. He or she gets your adrenaline pumping. You can directly or indirectly attribute all the bad things you know or did as a teenager to him or her.

 Eventually, you came to your senses and moved far away from this person, or your parents found a way to separate the two of you when they did the maths and realised that he or she was the reason for your sudden change of character. You somehow learnt your lesson, corrected your course, and made something of yourself. This person, however, continued down this rabbit hole until he or she had only stories of all forms of travails he or she has been through as a result of the lifestyle he or she has chosen and the attending consequences. He or she makes you feel uneasy or unsettled, so you keep as far away from this person as possible, but once in a while, this person will reach out asking for help. The story usually falls into these categories: Help me with some money to start a new business, support me to pay my rent, support me to pay my school fees, buy me a phone, please send me some money for food, I need a quick raise, etc. When you have to give, you sometimes would take pity on the person and give, but once you give, this person suddenly comes back a few days later to ask for more. In his or her head, you are a mark, and you have fallen for his or her latest con. If you get to spend a minute more than necessary with this person, you end up spending on things you don't need or doing things you don't want to do. You get to bail this person out of trouble all the time, and you cannot recount the last time this person was the subject of any positive news. This person is a sinkhole. No matter what you throw at it, it swallows it whole. You must learn to keep far away from some people, if you look as far back as you can, and all you remember is this person taking and taking and taking without once being of benefit to you in any way. It is not impossible for the person to turn things around, but he or she will have to be allowed to do it all on their own. The best thing to do for such a person is to keep far away from them and also give them no access to your finances. Some have been known to gamble away the hard work of anyone who is kind to them, and in extreme cases. Some have introduced their friend or relative to drugs, prostitution, gambling, and other vices. Once you have diagnosed a sinkhole, the best thing to do is move as far away from it as possible.
