Tell me about the strongest "supporting brother" you've ever seen?

I'll go first. I used to go home with a girl,
and we had a meal with her family.
After we finished eating, she looked very upset,
saying that her whole family was very dissatisfied with me and that we shouldn't get involved anymore.
I asked why? She said that during the meal,
when she mentioned that once I start earning money, I would buy her brother a car,
her entire family noticed that my eyes flicked a little?????
