Tonight I'll have nightmares with zombie-hoodies

As a personal quirk of mine, I consider zippers on tops uncomfortable and always choose something that fastens with buttons. I have a phobia that metal zippers on hoodies will scratch my face. Can someone please explain to me then, why I have so many of them? I spent all day putting away my summer clothes and generally sorting out my closets and I just realized that I reaaaaaaally must downsize before I move to Athens in February. God, I wish I wasn't so lazy for e-bay listing.
