I was wondering what the proper etiquette is for people who call your cell phone and don't leave a message. They will call, so it registers, but don't leave a message. I can understand if they know you well and you know them well...But what if you don't them? Do you call the number back? Do you just forget about it till they call again? Do you answer, even if you don't know them? I just don't know!
Just leave a message! Or don't call.
