im in the exactly same situation as u are and i dont know what to do either :(
I agree that it is best to talk to them- or you grow some balls and find other friends!<br />
there is nothing "whiny" about either choice-- but if you choose not to talk to them, work is going to be mighty uncomfortable for you! Life is too short to play guessing games with your friends!
You should have an open conversation with your friends and tell them how you feel, if they care about you. they will make sure to be more sensitive about your feelings...if not, you shall definitely find better friends, <br />
P.S: Engaging in an open conversation is always helpful, there is nothing wrong in it...speaking your mind and heart is all that is needed
