It's quite good. I like the repetative 'We/I need Charlie here.' Check your capital letters. Charlie and Molly should *always* have capital letters. So should I, I've, I'd all those words. 'If I hadn't lied, If i'd just written a letter' Didn't really make sense, could you explain it to me? Capital I in I'd, not in if.

good rhythm maybe better with alternate rhyme but apart from that gr8!
