cannot

What, you want to do it, but you can't?

You mean, you've tried it? No? How about this: try for a year, every single day. And after that, if you still can't, come, and I'll hear of your disappointments.

Oh, you don't want to? Because although you've never tried it, you know you can't?

Then please find another 'friend' of yours who would listen to your whines, repeatedly. Someone who would pat you on the head and says, 'Now now, you don't have to try to be better, even though you've not tried to, simply because you just knew that you can't. Right. You'll never be able to, so, here's a cookie." *Om nom nom*...

Oh, such love your friend has for you. He even gave you a cookie!
