What is so wrong with wanting new things?!?

Desiree • Due with my rainbow baby Aug 6th Derik J McMurray
Seriously it's getting on my nerves! All I ever said to anyone was I want a brand new Pack and play because my son will be sleeping in it every night and I want it new and clean and one I really want and a stroller car seat combo. I feel like I shouldn't even have to explain myself with that one and everyone is giving me shit about it. What is so wrong here?! I'm the one paying for it not them and it's not a waste of money because I plan on having my next child within the next 3 years so I can use it again. But because I said I wanted those two things brand new everyone thinks I'm being a stuck up bitch and every single thing I need has to be brand new when that's a complete lie. 
I don't even know why I'm so mad about it but I'm so sick of people saying how stupid I am for buying them new. 
Bought my stroller combo today btw and I'm absolutely in love with it!
But am I wrong for wanting 2 out of the millions of things I'm going need brand new?
