Climbing whatever, that is. I don't seem to be doing that as I'd like, but I do persevere. 'Climbing' is useful as a metaphor in terms of a means of achievement, like climbing a mountain, climbing a ladder, and so on. Not that I'm scaling Everest, nor want to (am very comfortable at my present scalable elevation of only 440 feet above sea level).
Not to say I feel like the always unfortunate Wile E Coyote in that his being successful will probably never occur, at least in capturing his speedy and elusive target. But he never stops trying, no matter how often he gets zinged. So it is that I must persevere.
And be honest, didn't you want Wile to finally catch and thrash that obnoxious roadrunner too?
Speaking of climbing and obnoxious, how about that felinus appropriately named Linus on top of the stack washer/dryer? They seem to have no issues in climbing to the top...
