Life can be divided into two segments: the period in which you were not worried about your gas pipes, and the period in which you became quite worried about your gas pipes.
I literally mean gas pipes; this is not about getting your innards checked. The other day, a letter arrived from the utility company, and it said IMPORTANT INFORMATION. You certainly want to open that, in case it says something like, "We've decided to move our services to an app through which you order gas whenever you need it. Think of it as Uber, except for heat."
There are people who would love that, because they could control their gas from their phone, which is the end point of all human endeavor. You could raise $25 million if you developed a cremation app that let people adjust heat and duration. But, won't the user be dead? Yes, but after the next round of funding, we hope to build scheduling into the app.
Anyway, IMPORTANT INFORMATION also could mean something like, "Hey, we know you were expecting lots of gas this month, but Bob in invoicing screwed up and we're, um, short. Like, we don't have any. Sooooo, our bad, but we're giving you a heads up so you can buy some sweaters. We will totally have gas next month, though."
Enough speculation. Opened the letter. It began thus:
"Important information concerning your responsibility for your gas pipes."
Hold on, what? They're my pipes, now? And I'm obliged to control them?
"You are responsible for the maintenance, repair and replacement of the gas pipes, connectors and valves."
