You don't need to worry about a guy noticing you. You should be the one noticing him. Every guy I've ever met says when it comes to meeting new people, girls have the better situation, because if a girl is outgoing, courageous, and confident in herself enough to talk to a total stranger guy, she obviously has the power to decide which guy she likes. Remember that relationships, especially new ones, are a leap of faith. You gotta take risks for someone else to trust you, and feel comfortable around you. I'm not saying point and demand the hottest guy in the room approach you, but don't be afraid to break the ice for no reason in the elevator. If a someone speaks to you, isn't it at least polite to respond? Shy girls and guys have to buck up that courage and be assured in that if chat goes sour, or the person just isn't your type, or you aren't theirs, drop it and move on. "hot snotty girls" and "good girls" who do get guys have one thing in common. They look like they don't need anyone but themselves to walk tall. Some hot girls end up treating guys like crap because they actually don't need anyone, and are not looking for a long term relationship. Hence petty drama, cheating, and general guy-abuse. Guys, and most girls, unless you're into the wounded type >_>, I like to think are the same in that respect. Shouldn't you have someone who is as awesome as yourself?
