Your life isn't the same as everyone elses. I volunteer once a week. By the time I get up there, do my bit and come home again, that's my Saturday morning gone. I'm also disabled. I live alone. So, unlike a lot of you, I've got to either do the housework or get someone to help me do it. And then there's the other things I do, like hobbies. And then there's the endless medical appointments, which depending on the hospital department, can take (including travel time) anything up to 2 hours.
Just because you have time to get everything done, doesn't mean the rest of us do.
Most of you on this website are students and not adults who actually have things like housework, shopping and other boring chores to do.
