I know some here seem to truly be interested in everyone's welfare. They seem to be really troubled/happy by another poster's health, life, children, job, sex life, worries, anxieties---you name it, they're very involved in "caring" about people that they hardly know.
I have forged some friendships, I've met some great people on this site. I've communicated with many nice people here. But I can honestly say that I rarely get deeply involved with most posters here. I like most everyone here but I don't love everyone .
