Thanks, everyone, for your words of advice. You had some great ideas. I know I am not the only parent worried about this subject. I wish we didn't have to worry about such things.
I am hoping whoever walked in last week is long gone...
My daughter has a dog (lab) that was absolutely no help at all. Either she is hard of hearing, having aged some over the last couple of years, or felt it wasn't her responsibility to get rid of the scary man! Her roommate cannot be changed as they have a lease together that is up in June, at which point they will be going their separate ways. My youngest will probably be moving in with her sister and brother-in-law, at least until another roommate can be found. I feel better about that. (Her roommate is a very sweet girl, but as Hillary put it - they are too young to see around that corner...) But in the meantime, she is scheduled for a self-defense class next term. What I am toying with is either a pepper spray or a taser. Neither is lethal. I do worry about it being used against her, but if it was protection when she needed it most, it would be worth the risk. Anyway, still looking at options.
In the meantime, Portland is warming up and we enjoyed a great day today. I am seeing daffodils, and all the trees are budding. By next month the city will be in bloom. I may have to visit again, just to feast my eyes. The shops on Hawthorne were fun and full of artwork. We headed up to "23rd" and continued our little shopping and eating tour. It was great to be with my daughters and grandson. Are we ever completely happy being too far away from our family?
