<prompt> Human: Im 21, taking on an internship for three months and it will be my first proper full time job. My salary will be 4500month for three months. I want to send money back to my father these three months because he has paid for literally my entire existence and I want to repay him as much as I can. Some context: My family is quite well off. My father has two cars for work and a recreational car in a big house in a nice area. I live alone in another state because of university and my dad sends me 3000month and opened a supplementary credit card for me and imposed no restrictions on me because I believe he trusts that I wouldnt abuse it, which I didnt. My father has never expressed to me that he expects me to repay him once I work full time, but I want to. And Im pretty sure the pitiful amount that I would be able to give him means nothing to him financially but I believe he would appreciate the gesture. After these three months Im going back to college for my final year of study so my father would probably continue to give me money as long as I ask for it. My question: how much money should I send him when I make 4500month? Or should I just not bother and save my money since its only three months of work? My rent and utilities is about 800month and I use my dads credit card he asked me to for groceries etc. so I would have a fair amount of money left to savegive some to him. Also have no student loans.  <response>: None. But you obviously have a cultural thing going on so you should state the culture to get opinions from people who have that specific experience.he has paid for literally my entire existenceThis is your job as a parent. I expect absolutely nothing from my children financially. I just want them to be good people who can support themselves and be happy in life. I feel like its my job to both teach and enable them to be capable of doing that.
