Amber, I'm glad the text convo DD had ended up ok, no real harm done.
That was one thing I liked when ODS was on my cell phone plan - even though I never read his conversations, we had the billing set up so I could see the numbers of the people he was texting. He and I would occasionally sit down together and he'd tell me who belonged to which number. AT&T lets you assign names to the numbers. So it got to where we could say, "ODS, why were you texting M at 12:30 a.m. instead of sleeping?"
But DH moved ODS to his Sprint plan because it's cheaper, and set up YDS on it too.
