Funny you mentioned that.
In infectious disease practice (45 years now) it’s not unusual to run across “normal people” who have had encounters, with their spouses and otherwise, who have gotten infected and then infect the “normal person”.
My very first syphilis case in practice was a kid (teenager) who went to Philadelphia and saw the Celtics beat the 76ers and to celebrate went out to get some “brown sugar”. You met this kid - you’d say - “nobody more normal than him”.
Darn, it’s a shame I don’t trust anyone who would vaccinate me against it!
Normal as in staying with one woman and not screwing everything in sight. That’s normal to me.
And the word I used was ordinary. Not normal.
To me it’s extraordinary to fool around or get a hooked or be a homoasexual.
