Fail #23?

Plenty of fails on Monday, but none since. The last fail may not have failed at all. I sent a text message to two recipients. I am able to tell as each message goes through and it appeared that it went to the first recipient and not the second. The failed text message signal appeared. I decided I didn't need to try to resend. But then the second recipient texted me back. So not sure what happened on this one...
