Eye contact, will make an excuse to talk to you, will do their best to touch you when possible but not make it obvious, will smile at you, will ask you on a date if they are confident enough and think that you will not turn them down... Loads of signs, but even if they do none of these it doesn't necessarily mean they are not into you. Similarly, they can do all of these and jus want to be friends for one reason or another... But we live in a world where sometimes you have to be the brave person who chases your dream, because it's not necessarily gonna fall into your lap... So why not try to become friends with your crush - you can make friends with their group of friends, hang out where they hang out, start a hobby that they enjoy... From there the possibilities are endless!!

Remember, you only live once and if you're not living on the edge you're taking up too much room on this earth!!! =P

Good luck with your crush,

Don.
