You're being a total slouch, but you're trying to act like you're not, even though you're clearly just avoiding work.
'I don't care if the homework is due tomorrow, but I'm still here trying to look like I do.'
'I don't care if you're late, but I'm still here trying to look like I do.'
'I don't care if the game is over, but I'm still here trying to look like I do.'
