My brother borrowed 5 euros from me. I was a highschool student, so I didn't have to handle cash all that often. I didn't mind if it took him a few days to give it back. We live in the same house by the way.

A few days pass by, and I ask him politely if he has the money. He tells me no, but says he'll get back to me shortly.

A few days after I ask him again, because maybe he forgot about it. He doesn't have it. No big deal.

About a week into this, I'm sitting at the table with my brother and my dad after eating, and I ask him again for the money. He gets annoyed with me and tells me (paraphrasing, it was a long time ago) "I'll give you when I have it."

I freak out, because I know that he could easily ask dad for some money to pay me back, but he thinks he doesn't need to, because, according to him, and he told me this, "you don't really need it right now."

I start yelling at him, telling him that it doesn't matter whether or not I need it, it's my money, and I want it. Then I demand he give me the money till the next day, by having dad give him some money to pay me back.

Now, him and dad are trying to quiet me down and saying that I'm being "unreasonable," because I don't need the money right now. I get even angrier, and tell them again "it's my money, and I want my money back."

In reality, it wasn't about the money, it was about respect (even if I didn't realize it at the time). My brother was only "forgetting" to pay me back because he didn't respect me enough. He justified not trying to pay me back by saying I didn't need it, but he wouldn't have thought that way about anybody else.

The next day, he gives me my 5 euros back. I felt a bit less disrespected, but that was the last time I let him borrow my money.
