Sam I Am - Friend lyrics

Now i am five now i have turned five i'll be with the big kids at school no more mom and dad now i've got to act cool not all smiling faces not all open arms i don't know this was your cubby hole now i have grown older now i've grown colder i'm here with these a**holes at work no more mister nice guy now i'm that jerk not all smiling faces not all open arms just give me my invoice slip
