Ok, honestly. Sometimes, it's not so much a matter of spending the entire 20-30 minutes actively "dropping the kids off at the pool". It's not like it's a half hour of continuous clowns exiting a volkswagon clown car, one after the other.
It's more like 5-10 minutes of "preparing", 5 minutes of actual "active duty", and then another 10-15 minutes of "afterglow". And with regards to the prep stage and afterglow stage, a lot of times, it's the only free time in a day I get to myself where I don't have my wife & kids bugging me to do something around the house, or they are stealing my ipad to watch movies, or play games, or look up something online. Between work, the commute home, preparing dinner, household chores, helping with homework, & bathtime/bedtime rituals, it's my little bit of "alone time". Don't get me wrong, I love all that stuff in my life, but everyone needs a bit of "alone time". Even if that "alone time" is involves me sitting on a cold seat with my pants down and legs going numb. Still my time... 😀
