Oh yes, so nice. I try to wait until I am physically sleepy to go to bed. And if it's late I send a text to my husband that says: Let me sleep until I wake up.
Yes it sounds like a stupid question, but it is an indulgence that not everyone gets to do. Many people have to work at a time that doesn't match their natural daily rhythm. My work schedule is flexible-ish, so sleeping later if I have to is no big deal.
