I also had an ENTP friend who used to do things like beg people for money to buy food he had never tasted before, take a bite and throw it in the trash and then pull out a $20 to buy what he wanted in the first place.
He would argue that it was just money and we were showing our bourgeoise tendencies by getting angry about money!:steam:
So I think you have less to be ashamed of than he did!
And we were all jerks as kids for some reason or another.
