I know a thing or two about computers. I think I may have frightened someone who had posted a comment on my site.
Those people that I have not met I tend to write back via email, to introduce myself. The last two people have not written back or visited since I wrote them. This it clearly not my intention, I just was trying to be neighborly.
I think it was my Mom who may have told me to be kind to your neighbors. (I may have learned it in Sunday School, which ever it stuck.)
Just because, I am far, far away physically and I am in the capacity of serving my country does not put me in that "category". The one, that you put "other" people in.
