I will be glad when they are caught, too.
If it helps, I do yoga and pilates in the coolness of an air conditioned house while watching television and that, along with a little aerobics, helps with the stress level when I can't get out. It will help you sleep better too, if you can find a way to do exercising in the safety of your place, Kate.
And if you can sleep better, the stress level will be more manageable. But in the interim, it's quite understandable that you are stressed. I know that I would be getting a dog and better locks and thinking about all sorts of issues we don't like to have to think about.
I'll keep you in my thoughts Kate and pray for your safety.
