There are some days where you are not feeling yourself and you do not care what anyone says. If you are having those days, directly tell someone you do not currently care and to get back to you when you are feeling better. If someone is talking non-stop about something that you do not care about, tell them before they keep going and bore you further. Try not to sound too annoyed when you are telling someone you don’t care as you can accidentally make them feel bad, or anger them. But sometimes you may have to be blunt if the person doesn’t stop talking.
