I view vegetarians as being unnecessarily fussy and daft. I have friends who are veggies, I will cook for them. Likewise, if someone has an allergy, I will respect that to the nth degree. But I still cannot shake my prejudice that veggies are attention seek-y or making a grand statement mainly cause most of my "veggie" friends stopped so they could stuff their faces with kebabs when drunk and said that they didn't eat bacon as a comment on society xD
Also, I am very, very judge-y about people who use text speak or lazy grammar. Even on things like Facebook. If you're dyslexic, fine. However, I am genuinely on the brink of removing a friend (well, friend of DH who latched on a bit) because her statuses make me want to throttle her.
All of this is wholly internalised and I would never say anything, obviously - tell me yours, no matter how petty / mean / judge-y they are.
