I used to know my personality, but now I can’t get my head around it

I have had a discussion with a new friend I made in Montréal, who told me she went to a speed dating event and it was a lot of fun. So she suggested I should go to one and I rapidly replied I couldn't attend such an event, not because I don't like the concept (I did say it was a weird concept, but hey, don't you agree?), but because I'm just unable to do so.
