I take notes and for dates I think are important I put them in my calendar, but I also remember numbers easily so dates aren't a challenge for me. I have Aphantasia & Prosopagnosia so I don't waste a lot of brain space remembering what people look like :D (Or names for that matter, I'm terrible at names). Seriously though, I would walk past that same co-worker in a shop out of context and not recognise them at all. Context is always important, I don't just randomly trot out dates because I can. I've never once had a person react negatively to me doing this. Its not like I see you for the first time in a year at a BBQ and the first thing I do is look up in my CRM my notes from the last time we met. I'm not wearing Google Glasses to tell me your name, DOB and family details. I met a former colleague a few months ago randomly in the street, had a quick chat and went our separate ways. Ten minutes later I looked at my calendar and realised it was his birthday; I didn't run after him to wish him a happy birthday, but you can be sure next year I'll remember his birthday without my calendar because of that day. I recognise some people might be offended, but my own experience and most of the literature I've read around establishing rapport, building emotional connections etc all point to people really liking it when you talk about them. So I will continue to use my method until evidence points me to someone else. I know I risk alienating people such as yourself but overall I feel I have better friendships and working relationships. I just hope if I make someone uncomfortable that they'll let me know, just as you did.
