Don’t Mess With Cows
If a cow is standing in front of your house in this manner, it can only mean one of two things: either you know where the cow’s calf is, or the cow saw you enter the house carrying a lot of milk. In either case, someone needs to take care of it before it causes a breach in the security.
You should avoid getting into a fight with cows. They are lovely creatures, but when things don’t go their way, they can become very angry and destructive. The fact that this window is made of glass does not make it an impossible obstacle for a cow of this size to break through.
