You really should say it. But if you really want to cover it up, try saying it in a different language.
text or flirt.
Be nice to him by doing random acts of kindness for him.
you tell them there a really nice guy but you dont really like them
write them a note
Ask one of your friends to go do it for you.
Spend time with her. Listen to what she says. Be interested.
Get your friends to say it or give him signs you like him like blowing a kiss
There's really no way to get around that one. You're just going to have to be bold and daring here. But don't say it like it's a joke. Be sincere.
no its not you could be embarrassed if the dude rejects you, so wait a while more then tell him your feelings or if you are brave ask him out!! ;)
you can't really, you just have to tell 'em.
you hint it to them very slowly across time
