Well, my mother-in-law would have to make a day trip to drop in
, but I'm sure she calls her friend next door before going over, anyway. I don't mind if people drop by unannounced, as long as they are Ok with taking me the way they find me -- IF they find me. I do tend to call first before I drop in on anyone, though, even if it's just from outside their place on the cellphone -- you call 'on spec' and take what you get -- sort of the same as ringing the doorbell, except that the person is free to say no.
