No I make sure I don't look at them once seen as I either feel sorry for them (if they have an affliction) or don't want to give them attention (if they are trying to shock people with the way they look)
I probably did when I was young,but I cannot truly frecall doing this as an adult!! Maybe it is due to having friends in wheelchairs and with other physical afflictions which normally would make them stand out. I know when I had my brain tumor removed,others looked at me as though I was a bit weird,and it is NOT a nice thing to be on the freceiving end of. On my worst day,I made some terrible comment to the person giving me the odd look,that at least I have proof that there IS a brain in my head!!!! It broke the ice and we both started to laugh,even more heartily as passers by stared at BOTH of us as though we were two mad peas in a pod!!!
Nope. My parents would have never allowed it. If I look at somebody who looks different I always smile at them as well so as not to appear rude. Differences don't bother me. I agree with fran - never look at the people who are attention seekers.
