A friend of mine usually ignores me and asks me for help whenever something happens (involving money). What should I do?

Your friend usually ignores you and comes to you for help when he needs money. It seems that your relationship is very general. He doesn't usually contact or walk around. He thinks of you when he needs money, begging for help at the last minute, and not burning incense when he is free. This kind of person can't lend him money even if he has a big thing. He doesn't take you seriously at ordinary times, so it must be very difficult to pay you back. Stay away from such people before it's too late.
