I update my laptop on the second Tuesday of the month. When I did computer support at my job this was a requirement. Microsoft refers to it as Patch Tuesday. Because I keep my computer updated the monthly updates rarely takes more than a few minutes. I don't know how long it has been since the church's laptop has been updated. I do know that I just finished installing the big update that was released in Oct 2018. There are still several updates in the queue.
We have another storm with a possible tornado on top of us. I'm watching the TV showing the hook & sheer on the radar and the helicopter taking pictures of it. I can see the helicopter from the window in my living room. I know I'm safe because the helicopter is almost over my house so the possible tornado is away from it.
And yes, my cellar door is open and less than 20 ft away. It will take us 30 seconds or so to get in it. There is NO WAY we can stay in it all the time we are under a tornado warning.
I do have a fear of being trapped in the cellar by the home falling down on top of the cellar door. We have a pickaxe and various tools in the cellar to help us get out if that happens. I remind DD at every storm that I'm counting on her to come dig us out if our home gets hit.
