Her name is Edna but you call her Gran. It's what you've always known her as, though if you want to get technical she's your stepmother's mother.

So when she asks you to come by and help her with something on a Sunday afternoon you're thinking you might need to change a lightbulb or fix a dripping faucet.

It's probably the last thing in the world you're expecting to be asked, but... Well, Gran wants you to help her set up a Tinder account.
