Personally I wouldn’t take the high road. Not in this situation at least. When someone decides to tell lies and stuff like that they better expect that the universe will respond.
You probably didn’t think it was a big deal because it’s not a big deal. Guests rarely used horse anyway. I mean have you ever actually used a drawer and a hotel if you weren’t staying there for quite a while? I’m guessing probably not because it’s a good way to forget stuff LOL. This lady is just an a******.
