I don't respond to anything on Facebook. It's not a healthy place. There are certain subjects that interest me but I stay away from messaging.

Usually I don't notice they have seen them because I send a message and don't look again. If I notice and it was a question, I give them a couple of days and if they don't answer I think we're done and this person doesn't want to have anything to do with me. If it isn't a question, I just conclude the conversation was finished and they have nothing else to say.

Depends who they are. Im not bothered if its just acquaintances. Id be annoyed if it was family.

It's ok. I try not to worry about that.

Fb? Why?

Do people still use Facebook lol

Depends on level of acquaintance.

They don't want to be bothered. Leave them alone.
