I paid for materials for my girlfriend to make some crafts and now I'm having the urge to sell what she made.
Why would you want to sell your girlfriends crafts?
I'm going to sell them and buy an Xbox
I understand you want to get an Xbox but you should pay it with your own money. Your girlfriend probably will get upset that you are selling the stuff that she is making.
We have a lot of money. I'll buy it when she is asleep. What's the big deal
The big deal is that she could potentially be really attached to what she created. I don't think it's worth selling it and causing a potential fight between you and your girlfriend.
