When I was 7, my grandmother bought a Power Wheel ride-on Jeep for my cousin, and got a little die-cast Jeep for me. At the same family Christmas party. I think my other cousins also got cool shit, while my sister got something small/cheap like I did. Can't remember what exactly, the only details I recall clearly are my cousin's Power Wheel and the gift that I got.
I think grandma and my dad (her son) were feuding at the time or something, and I guess she wanted to be petty by giving us shitty gifts compared to our cousins. It was one of the first times I realized how shitty people in my own family could be.
This was 30 years ago and I still get pissed off thinking of it, even though my dad and grandmother eventually made up, and she passed away almost 20 years ago.
