Confused about Facebook?

[Samantha]

So I send messages to my friends. It says it sent but they don't get it!?!?!
No that's not it..They're not lying because when I refresh it says it didn't send...

Well first I woul say just double check and see if your sending it to the the right people lol. And maybe Facebook is just glitching, if its from a app the uninstall then reinstall. If not just try again later.

Take a screenshot and tell them you did sent it.
Might be the internet problem...

Agree with the two previous answers, just want to add something, they might lie to you.

You can check whether they have seen it or not by seeing the last message you sent to them, if they read it, most probably you'll see on the bottom of that last message "Seen at...". I said most probably, because sometime FB don't correctly show that or after they read it, they click 'Mark Unread'.
