I don’t wear deodorant on the weekends, but I do when I go to work. Unless you’re going to start living outside, you should probably find a deodorant that works for you and start using it. If someone is telling you that you smell bad, especially someone who cares about you, then take there advice and do something about it.

You say you don’t really care about your smell, but your family obviously do. Since you don’t care just start using some every day. It makes a world of difference and you don’t even have to use that much.
