Last year, during the bad time, I would hear someone stomping around behind me when I was at my desk at home.

I have my back against a wall now so that won't happen.
I hate it when people are behind me. At my office they oriented my desk so the people sit and wait behind me. I can't stand it. I have to turn my chair so they are not behind me any more.
And people walking behind me unnerves me. At work if it's someone I know like a co-worker I'll let them catch up to me. If it's a stranger I just feel like I have to keep my eye on them.
