Yes, have a snack, cup of tea/coffee - clean something - anything to keep you busy. Just wondering how long are you at your parents for - is it something you look forward to or dread? Just thinking ahead in case the AV says you deserve a drink afterwards - that was always a classic for me - rewarding myself for doing something I didn't enjoy with a large glass or several.... What have you got planned for the rest of the week - have something to look forward to - thinking past the moment to something in the near future is helpful.
