My friends end up knowing when I have a crush on someone because I'm so obvious about it etc. and they may try and help out (e.g. optimal movie seating) but I would never ask them.

Earlier this year a friend of mine recruited me to try and do this. It was super awkward and fell through pretty quickly. Granted, I half hoped it would be like a teen movie and the guy would fall for me instead because that would have been much with the lawls.
