You'll have to define "normal", Dugh.
Hmmm... this reminds me of a story that happened to... a friend. One evening, he went to his parents' house. He saw one of his mom's sisters was there. He can't stand the woman, wants nothing to do with her. Didn't even say "hello" to his mom, let alone allowed the other woman to see him. I took off... I mean, my friend took off immediately.
