Toys!!!UGH!!

Seriously I can't stand toys.  They appear to have taken over every viable space of my house...that and laundry!!  Maybe things wouldn't be so bad if my children would pick up after themselves.  I hate that I have to nag and hound them to get them to pick it up.  Why is it so hard to instill that when you make a mess of toy's you pick them up.  An even better thing would be if they would put what they're done playing with away before they got a new one.  Is it at all possible...is it just me and my craziness...do children anywhere do this are we all together and they unite against us?
