What do you think of me selling yeezys my friend lined up 40 minutes for?
Why do you need to sell their yeezys?
I want to earn more money and I like money a lot more than my bfs.
It doesn't matter if you like money, you still should have morals and consideration otherwise you will be seen  just selfish and greedy. That is not your property, so you have no right to steal it and scalp it. It is disgusting, rude, and it's like betraying your friend for your greed.
I'm doing the right thing to earn money with what I like the most. It's their fault for lining up 40 minutes. They don't even have money.
You should not sell something that your friend believes is sentimentally valuable. This will lead to problems and conflict between the both of you.
