Most people just need or want to talk, right?

You'll see people on Reddit asking questions that they know the answer already for example: should I lose weight? ( They know that they should lose weight ), is my room messy? ( They know that they should start cleaning their room ) Or for example again when you there's someone having new shoes but they'll get no attention by friends or in public so it get posted here. Hope it makes sense and yh ik I'll probably get downvoted.
