I would have to admit, it is really impossible not to judge one by their apearance at first. It is like a natural instict for me and others to do so, however that isn't to say I'm not interested in getting to know them personally. A first impression on an individual is always given off by their appearance, it is what happens. Regardless of how they look or what they may express outside, they could be entirely different from what they might be like on the inside.
I always give the chance to get to know someone, it helps myself and the other become connected or get to know one another apart from what we see outside. Whether it be in a relationship or friendship I always enjoy getting to know one on the inside. Yes, I'll still judge them on the outside at first meet, but overtime I come to learn more about them. As long as we get along, we have those LoL moments, and share interest in something, and build trust within each other, then they will always be a great friend in the long run, no matter how they may look.
Of course, if it were to be a love relationship, of course I would want them to look good as I would expect they may look into the samething for me.
