Nope... of course not. Buuuut... they'll tell their children that they're beautiful. Of course they're not going to tell them they're ugly. But then again, it's their parent's' genes fault if they're ugly... so... Why breed if you're scared of having ugly children?
My Mum does but reading this I just remember her telling me that in the hospital when I was born she was worried about me getting switched because she thought all the babies including me looked the same lol :')
