I don't think they get better about this as they get older, I think we just get better at putting things where they can't get to them. I USED to leave stuff on my nightstand all the time, (chapstick, scrunchies, small book light, gum..ya know stuff) but now my night stand is clean as a whistle at all times, just the alarm clock

I just look at it as the added-value in a yorkie...they make me be much neater!
