What happened......

Well me and Kelsey spent the night at my grandma's house and when my mom came with Conner and Brennan at 1:00 for them to go swimming and my mom we all got home at like 4:00 and this was there when we got home! We dont know if someone threw a rock or a bird accidently flew into it?? Who knows but the other day we got it fixed so its all better!!!
