The fact that senior citizens grew up in a time when a rotary phone was a luxury, you have to cut them a little bit of slack when it comes to those new-fangled cell phones available now.

And just like texts from Mom and Dad, the grandparents never fail to provide entertainment.
Check and checkmate.
You do only live once.
