If someone owes me money and ignores me, I consider him untrustworthy. I know the feeling of having to wait for (significant) amounts of money, as it happened IRL. It may not be a concern to the person who has to pay, but waiting for your money and not knowing if you're getting scammed just feels bad.
I did lent money to a few people in the past which I didn’t get back to a few i told don’t need it when i saw they couldn’t send it it. But an african friend did gave me the amount i was owed (this was when i was in uni).
Then there was one classmate asked for my number in class and called me in the evening asking for a few bucks with reason(“I need it to pay it for an application form my credit card is not working, he was indeed from a different region”) it was not a big amount so i gave it to him thinking he was in need so i should help him.
I didn’t ask him for money for a few months until me and my friends were out to watch a movie.. I called him and asked him for the money he gave me bs excuses.. his credit cards are not working, etc and asked me to verify it.
To my wonder a friend told me he also asked for money from other people the same way and he called his. They convinced him then he paid him back. The person who paid back told me who asked him to pay back is a “Sweet knife” 😂
We met again at a restaurant and he asked me to join him on a business but i had other plan a bad feeling about working with him, he will cheat for sure in the business so I refused without telling him the reason, he looked sad, we shook hands and that was the last time i saw him. I think he will get in trouble someday with behaviour not to mention he was also got beaten by some by guys in the campus for some reason.
Well, experience with everyone is different and it’s hard to tell who to trust in short term.
