Remember when you used to want this toy figurine, or remote control car?
It’s still the same 20-30 years down the road. But this time, you want the actual sports car or the sound system which only 0.01% of the world population can discern the distinctive treble it produces.
Relationships between humans. The same as well.
In primary school, I don’t like Don because he takes my colour pencils without asking me. I don’t like to be friends with Sherry because she always snatches my friends.
Grownup version would be like. Tom’s a dick because he always poaches my customers. I hate Gina because she always takes credit for MY work whenever possible.
We never grow up really.
