I'm going to wear headphones while getting my nails done and for other errands
Why would you wear headphones in the middle of daily errands?
I just don't want to be bothered by other people's conversations.
Wanting to be left alone while doing errands is fine. It can help you to focus more and be more efficient.
I don't want to listen to other people, I just want music on.
I don't blame you. Just remember to take your headphones off while you're driving.
