I think the reason why people ask these kinds of things when they do, is because it is on their mind at the time. People are generally focused on themselves, so the questions they ask and why they ask are selfish. This is what I meant by people asking another to change for their own benefit, not the benefit of the one changing.
You can try pajamas or sweatpants instead of pants, they might be a little more comfortable and acceptable :)
I have stitches in my legs, so I avoid them catching on anything, because they are still quite tender.
But in my house, no pants is acceptable. :)
