On page 344 of The Final Days, by Bob Woodward and Carl Bernstein, we read:
"As was his custom, the President had not called for anyone to come. When he wished company, he simply made himself available."
somewhat like this. I usually don't call people, asking them if they
want to get together with me. But I have done so in the past. People
are busy, and so, if I don't call them asking them if they want to get
together to socialize, the socialization probably won't happen. But
people have called me sometimes, asking me if I want to hang out; in
those cases, I either say yes, or I try to find some excuse to say no
(since I'm not in the mood to socialize). I guess that my point here is
something that many point out: that, for a number of people, initiating
and preserving relationships takes a conscious decision, and effort.
the past, I have simply made myself available to people when I wanted
company. Sometimes, that works out. If people are watching TV in a
room, for example, it's not overly awkward for me to walk in and to join
them. But, at times, I have made myself available to people when it
wasn't a particularly convenient time for them. So live and learn!
