On an unrelated note, this Remote Doorbell app doesn't seem to do anything. I keep hitting the button and nothing happens.
Anyway, back to Starise and his issues. I wouldn't be too concerned. It's probably nothing. Well, it could be something, but that's not very likely. I mean, obviously, it could be that there's an invisible portal to an unseen realm cleverly hidden somewhere inside your house. I don't know who or what might be ringing that bell, but I'm guessing that they don't like to be ignored. I'm not saying that all of them are fanged, severely deranged, and absolutely terrifying with any object sharper than a dull spoon, but there could be a few. I mean, who else would you expect to find lurking behind an invisible hidden door? You'd like to think that they'd give up and go away, but, deep down, you know they'll be back and they'll bring their friends. In the event that they work themselves into a frenzy, that door may not hold. If, I mean, When that happens, you do not want to be home.
Of course, none of that is likely. I'm sure you're probably safe, more or less. After all, what are the odds that two of us would have that exact same problem?
Hope that helps.
