Let me introduce you to Alphie. Don't let that, 'who me?' look fool you. He's a cranky, calculating garbage can that causes me more frustration and grey hairs than both of my children combined. He refuses to do anything you ask unless you have a steak in hand or a piece of cheese.
And smart. He goes outside and barks and runs off if you try to make him come in. The only thing he responds to is food, and he's selective. Don't give him shit, because he'll just go back outside and bark until he gets what he wants and if you think you are on to him and refuse to let him out he'll leave a log in your basement. Anyone want him? He's free.
