This happens? I guess then we must not be very social people. Friend is a matter of definition, there is one non-relative who relatively frequently calls her the phone, for me that is zero but OK as never pick up the phone anyway, and she has about two, I have about three non-relatives who reply to emails or facebook messages although rarely initiate the exchange themselves. I guess these people can be considered friends, but the definition may vary. In my experience, socializing with people at work does not carry over into socializing after work, I think people guard their privacy rather jealously and we too, I remember two occasions in five years non-relatives entering our apartment and it felt awkward for both. For this reason, as socializing with coworkers does not carry over into evenings, and not really having hobbies or meeting people after work, the people mentioned above who can be defined as friends are former classmates, and as we approach 40 that kind of number naturally reduces.
This is why it is very important to not stay home from work. BTW my mothers case was exactly the same in the 1980's, staying at home and occasionally talking on the phone with 1-2 ex-classmates, so she welcomed when she was offered to open a fast food stand and talk to customers. Socializing at work and being home with the family in the evening and weekends can be a tolerable combination. No idea what would be more than tolerable, I always figured it is more natural to hang with relatives, perhaps kinship based tribes should be reinvented. (Not necessarily about "blood", but more about having shared role models and so on.)
I've seen occasional suggestions that extended families are having a renaissance in the UK & US, if that counts.
