"Hell hath no fury like a bean gone bad"....read on

Two days ago I was working on cleaning my room when I went to look out the window. I notices some black dots on it so I went closer. Upon reaching the window I discovered that there were tons of ladybugs just hanging out on the screen. I have a few pictures that aren't great but you get the idea. I counted and figured that there was about 18 ladybugs just chilling out on my window. Given there were probably others that I couldn't see around the frame. But it was wild. I heard that they were good luck. The lady bugs have come for me.
