I don't even know you..............
I don't think you are..
Because you believe me.....
i don't have any reason to think you are a loser. maybe you want to give me a few reasons.
I'm sorry I don't know you, so i can't have that opinion of you.
errr... this is awkward :/
I never said I thought you were a loser. I don't know you but I doubt I would come to such an extreme conclusion.
Because you never learn
Because you found something better than that which you lost.
