a very interesting topic indeed!
i would start up with a famous saying "appearances are often deceptive", and i agree with it. i have seen and met many ppl who think highly of themselves just on the basis that they are goodlooking and smart, it does not make any sense at all.
i will only question that what is ur own? looks are god-gifted. what the other person does to make it worth-looking is the real person but yes ppl who are pretty and smart they are very good criticizers. they think it to b their duty to degrade others by bringing out flaws with eyes, nose, being short, being tan. and god knows what.
i love average looking ppl who have all their own. i have found them lively and pleasent to talk too and yes at times the so-called ugly ones also supersede the rest.
