I can count working in dd's office as my declutter project today. OY! There was a lot that just needed to be throw away or put away somewhere else. She shares a large closet and has room to put a lot of project materials away but hasn't. I moved some stuff there so she could put away a very large box of the sunday school water bottles - it's been sitting in her office I don't know how long. (The closet needs a sorting also.) We gathered up the purim stuff and got it into a box for storage for next year. I got her table top cleaned off and physically cleaned. Got her to put away stuff stuck at random on top of her bookcase. She says other people bring things in there and leave them - I'm sure that Sunday school and Hebrew teachers do that some, as well as members. There are some little games that someone probably found at a yard sale.
Not sure she will invite me back...
