I totally understand that. It's the worry at how vulnerable they are that would eat away at you all the time and make you reluctant to venture out for any reason at all lest you bring it home with you. I felt strange just yesterday going down the street at lunch to Bed Bath and Table, though I only went to buy Mum the matching European pillow covers to match the duvet set she bought from them online (for some reason they wouldn't sell them online!). Even though it was only yesterday it already feels ages ago because I worked from home today.
