Communications to ignore

Today I learned that SMS is the new "to be ignored" form of communication. Three people who profess to be ... well, at the very least, good friends... of mine are not responding to SMS but are definitely awake and on social media. One of those I expect. All three, I didn't expect. (Edit: A fourth was responding with alacrity, so while there may or may not have been a tech glitch, it wasn't ONLY a tech glitch. And I did get a big flurry from my family, too!)

This used to be email. Send mail, maybe don't get a reply for a while. (I particularly suck at this lately due to very low time at a desktop.) Before email it was voice phone calls. Now I guess text is in the same bin.
