Erm...he's...er...um...well, he's quite...erm...er...um...

No it's no use, I can't think of one positive thing to say about Tim.

He loves his mum ?

OK, yes - he loves his mum. Now think of a second positive thing.

he loves his girlfriend?

he hasn't killed anyone.
well there was that one time but that was ages ago now,since then he hasn't killed anyone at all.

also, like he says, he is NOT arrogant.
