Ever noticed how when someone has an issue with something, an expert in that field walks into the room, and the issue resolves itself?

I have seen this with computers, when my expert dad has appeared, I've heard of how an electrician walked in and a wall plug issue got resolved without him needing to actually do anything but enter the building, and I've often heard of it when it comes to cars and mechanics, although these issues might come back after the mechanic leaves 😅🤣
