If you work, sometimes it can be nice to zonk out and relax at the end of the day for half an hour or so. Or if you're a SAH parent, it can be nice to just take a quick break... and hand the LO off to your SO when they get home from work!
Mrs. Bee and I both focus on the kids for about 3-4 hours when we stop working... then we get to rest. A downside of having two working parents!
Do you need time to wind down at the end of the day? Do you or your SO take a quick break at the end of the day before entering the dinner/bath/bedtime stretch?
