Was this paint brush on the table when you came in here? NO! Then it should NOT be on the table when you leave. Do I come into you house and take your ketchup out of your refrigerator and leave it under your pillow? No, because I clean up after myself! If I borrow something I’m gonna put it back! I get paid the same regardless whether we do paper mache, whether we do drawing, whether we paint, or whether we do bookwork. So if you come in here tomorrow and you’re doing book work, don’t get mad at me because OBVIOUSLY you can’t clean up after yourself.
