Question: What to do while waiting?
Do some chores around the house, read a book, watch TV (set a kitchen timer so you don't forget to take the trays off after 30 minutes). Practice a musical instrument. Try sketching. Learn to knit, crochet or do embroidery and use this time to get some uninterrupted time to work on a project. Check out your clothes for minor repairs, missing buttons, etc and take care of them so you aren't surprised when you pull something out of the closet, then realize it has a split seam or a dangling hem. Meditate. If you think about it, I am sure you will find a ton of other things to do.
It's the perfect time to do some things around the house. I would do some cleaning or a load of laundry.
