Not your beauty/teeth brushing thing, but things you do downstairs before going to bed at night?
Mine are:
Bring any laundry that's drying outside on the clothes airer in to the kitchen.
Put food scraps from dinner into the food caddy. And any other rubbish in kitchen is in bin.
Check back door is locked.
Open washing machine door and powder drawer to prevent mould/smells.
Make sure the dish cloth and washing up sponge have been wrung out in boiling water and are drying.
Get myself a large glass of water with lots of ice.
The washing machine thing is a little tip if you want it.
