No one enjoys doing laundry (well, at least know one I know), but unless you live in a nudist colony, cleaning clothes is a necessary evil. Getting it done, however, seems more like a punishment than a normal part of adulthood, especially when you're a parent. That's probably why there are some weird things moms do when they're doing the laundry, and that's definitely why those weird things make sense. Getting through piles upon piles of laundry, day in and day out, usually forces you to get creative with both your time and your imagination if you have any hopes of making it through that massive piles of clothes.
There's a lot of weird things parents do just to get through the day, and doing the laundry is no different. Household chores are the bane of every parent's existence, at least until they're kids are old enough to participate. Until we're able to teach our children to be independent enough that they're able (though, not necessarily always wiling) to fold their own laundry, that responsibility is, unfortunately, on our shoulders. That's probably why so many parents are left with a choice between going commando, or developing their own unique (and weird) coping mechanisms to get through the redundancy of washing and folding the same clothes over and over and over again.
Of course, it's not to say that dads and/or any other parenting partner can't pitch can't do laundry, too. I mean, washing everyone's clothes is definitely not the mom's responsibility, just because she's a mom. I know plenty of parenting partners (regardless of gender) that do the following weird things to get them through a few laundry loads, too. However, if dividing up certain responsibilities in your family means that you're doing most of the laundry, and you do the following ten weird things all day every day, trust me, I get it. Do what you gotta do, mom, because laundry is the freakin' worst.
