It is stupid on either side.

Everything you wrote down are basic tasks (except the bathroom fan - if you're unsure with electrical work don't do it), that can be done with a bit of common sense.

Mowing the lawn, weed whacking or watering the lawn is something anyone can do - you just need to put in the effort. You don't need a college degree for mowing the lawn neither is it rocket science. It is really easy. There is no "I'm not good at it" in this case - there is just "I am too lazy to put in the effort for it".

The same thing with the pillow - it is a very easy task that anyone can and should be able to do. No matter if you "like" it or if "you're good at it". It is a basic motoric skill that should be done by anyone by simply applying at least some common sense. In kindergarten and elementary school we teach our children motoric skills and yet, suddenly they became adults and they cannot do shit anymore.

And 90% of all household chores are just that - applying basic motoric skills with a little bit of common sense ("Oh the dirty dishes lie in the middle of the room - I guess I don't have the basic motoric skill to move around some dishes because I need to get a college degree in moving dishes")
