Ivy, when I was 11 and my dbs were 9 and 6, my dad worked away from home so mom, the boys and I spent the summer with him. They dropped us off to see "H ush, H ush S weet Charlotte". It was a scary movie and I sat in the middle and had my arms around both boys. We spent a lot of the movie huddled together. When it was over, it was dark, we were in a strange town and our parents were late picking us up.

My dm was mortified that they had dropped us off to see a horror movie and didn't know it. Years later when I met dh, we talked about that movie. His dsis had went to see it with a bunch of friends. They had walked to the movies. She was so scared that she ran all the way home and didn't realize until then, how fast she could run.
When we were newlyweds, we were watching TV in bed and a scary movie came on. We spent a lot of the movie with our heads covered up. We didn't know the name of it but a few years later, we found out it "P sycho".
I do not like horror movies but since I have married dh, I have watched many war movies. But after I have watched one once, I am done. He has some that he has watched so many times and continues to enjoy them, over and over and over.
