Did you know that I'm addicted to getting new shirts?
I didn't know that. How often do you wear the shirts that you buy?
That's not relevant. My addiction is to buying shirts not to wearing them.
It seems irresponsible to spend lots of money on shirts that you don't wear. You should try to save your extra money, or spend it on things that you'll actually use.
I am very careful not to waste money when I buy shirts. I research them before I buy.
Even if you're getting good deals on the shirts, buying them and then not wearing them doesn't seem like a reasonable way to spend your money. Have you at least thought about wearing them and getting some use out of them?
