Grandmother knocks on my door about 15-20 minutes ago.  I'm thinking, What-what-what???  Someone on the phone?

No.  "Can you take my blood sugar?"  Really?  Couldn't this wait.  How rude.

Meanwhile, I've made the decision to keep the modem plugged in the next few days, at least.  Don't know why this is making me nervous.  First of all, I've already done it one night.  Second of all, I'm paying for Internet.  Still, in the back of my head I'm thinking I'm going to have a confrontation with My Father over this.  Wish me luck.
