You’re still not 100% sure if it was a male or female but you are 100% sure how many kids he/she has?
Anyways, to keep the fun going longer I’m going to decline to prove myself to you since I know with certainty it is what it is. But since I’m a nice guy or gal (depending whether I’m a gentleman or lady, as ubiq would remind you), the next time I see you at a Shabbos seuda I will definitively identify myself to you by specifically mentioning the coffee room. (That isn’t a “nisht Shabbos geredt” topic, right?)
That’ll leave you no more room for doubt.
