What's your most overused word and/or phrase? I say I don't know and nothing more than anything. Half the time I say I don't know I do know, but just don't want to say it. I will never say my opinions or the correct answer unless I am absolutely sure it's correct. Oooh and Nothing. Nothing nothing nothing nothing nothing. My day is filled with nothingness. That's why I hate questions like : "what's up?" nothing. "what did you do today?" nothing. "What are you doing this weekend?" oh nothing. So I don't know? Nothing!
