katiekitten,
Like when you meet someone very genteel and terribly respectable, and you sort of feel like a bit 'rough and ready' in their presence.
One of the best things you will ever do for yourself in this life is to turn this around. As you said,
But however shoddy I feel by comparison, I could NEVER want their sterile safe middle class existance. Its so drab and cold and tediously boring. I feel sorry for them really aspiring to such dullness.
All you have to do is dedicate the self-shaming parts of your brain to making the squares realize this. Repetition for emphasis:
I feel sorry for them really aspiring to such dullness.
I feel sorry for them really aspiring to such dullness.
I feel sorry for them really aspiring to such dullness.
