Unwanted Piles

I hate piles: piles of clothes, piles of discounted stuff at a store, piles of unwanted stuff, and especially piles of mail. It just gets overwhelming at times. Where do you put the piles? There's not a good place for piles.
When my kids were at home, clean folded laundry was piled on the dining room table, with the delusioned thought that they might take it upstairs to their rooms. The only one who enjoyed those piles was the cat. "Ahhh, a nice fresh pile of clothes in which to bask."
When I see piles of stuff on sale at a store, I can't even go there. If I do, I end up orgainizing the pile. "Okay, this is a small, it needs to be over here", etc. I even do it at card shops. "Oh, I just read that card. It doesn't belong here, it belongs - oh, where was that card?" And then I search until I find it. Am I alone in this obsession? One would certainly think so the way the cards get so out of whack.
Piles of unwanted stuff tend to go on a chair and/or floor of my bedroom, my logic being I may as well wait until I have a substantial pile to take to Goodwill. My mother always had a Goodwill bag in her basement. But I don't have a basement, darn it.
The mail piles are crazy. Who has time (or wants to take the time) to go through all the junk mail you get? Yet, I won't just throw it away, unless I'm on a rare cleaning frenzy. Fortunately, I'm not a grocery store coupon clipper or I'd really be nuts. However, I do tend to save discount coupons for restaurants and clothes. It's pretty pointless because most of the time if I'm at the store, the coupon is still in the pile at home (probably expired). But then there's the never expire coupons such as Bed, Bath & Beyond - how many of those does one need? Call me, I've got several :) What about the important piles, like bills, and now, end of the year taxes? Better have a special pile for them. I also tend to save small catalogues, as they're kind of fun to look through on a boring night of TV. Then I'll turn the page down on something I think about ordering, only to throw it away when the newer version of the same catalogue shows up. ERRRGH!
What makes me post about this is that my son & daughter-in-law are coming to visit this weekend. Ahhh - time to get rid of piles, right? And I don't think putting them in the dryer is an option. Better go, Piles are waiting.
