I had a date which went well for the most part. Pretty standard, walk and a coffee. Conversation was alright, we shared a fair bit about ourselves and made each other laugh a couple of times. We shared a hug when we left and everything seemed fine, like any other date really. Then a little while later he texted saying he enjoyed meeting, but he was curious if I was nervous or just reserved in general. I didn't quite know what he meant, so I asked what he meant and the best I could get out of him was I am 'hard to read'. I've never had this before, and I'm confused as I feel I was actually quite open when we met and the conversation seemed engaging enough for the time we spent. He didn't try to kiss me or anything so it's nothing like that. I'm just wondering what he could have meant, I know it's a bit hopeless posting as you can't exactly watch the date back but has anyone ever been described like this and what kind of thing does it usually refer to? He did ask if I wanted to meet again, but I feel a bit put off by it, as in the beginning it's more standard to hear positive things whereas this just leaves me feeling a bit confused!
