What for?

Can't understand some ppl who pretend to be nice when you clearly know their true intentions. Why can't they just be themselves instead of trying to be other ppl? Why can't they just be happy with what they have instead of stelaing other ppl's thunder? It is that important for them to be in the limelight all the time. Really dislike that attitude of some ppl trying so hard to prove that they are better than others. No need to prove one. If you're good, you're good right? Scrape the i'm-better-than-you attitude and maybe other ppl will find ppl in this category more approachable. Don't you think? Cheers!
