Thank you all for your good advice.
I didn't even consider calling the police, not sure why.
I do not have any type of camera outside. I imagine if I did it would be easy for the criminal to rip the camera off or cover it. I have thought of getting them, though.
I didn't want to open the curtains, as was said, the person would have seen me. I didn't want to call out to ask who it was, again, they would know I was a woman, alone.
I didn't put the inside lights on even when I got up at 5 to walk around the rooms. Just in case.
I don't have any guns and the only weapon I could come up with is a can of some type of spray to try and blind them temporarily. Probably not very useful though.
There was a gutter cover salesman who wouldn't take no for an answer, even though I had a sign on the door to not disturb. That was shortly after my husband died. He was relentless and finally I told him to leave.
That night I was fearful he was coming back and I went to bed with a can of air freshener. Laugh. I was very fragile at that time.
Around that same time I had been helped by a retired plumbing contractor working in Home Depot. Some how we got around to talking about our recently deceased spouses who both died at the same hospital.
I told the man I had a glass windchime on my kitchen door in case someone came in I would hear the chime. In his bluntness he said most burglars work in pairs and I would be helpless.
It's been a hard eleven months since my husband died. It's things like 430am doorbell ringing that gives me a reality check.
I can't reply individually, I am getting a bit teary. Think I will try and stay awake as long as I can.
Can't live in fear and can't control what other people will do.
Thank you all again, it's helped me.
