IdEngager is occasionally not, well, engaging

[IdEngager]

I've been thinking about this lately cause over the last month or two, a lot of my social interactions/dates/evenings out haven't been horribly stimulating or exciting, and I feel like most of the problem is on my end.

Growing up, and probably now, I could hardly be described as a people person. I've always been a good listener, but I've not really one for small talk, and I'm not really that guy who brightens everyone's day by being chipper or anything like that. I can be moody and aloof, and sometimes I just want to get through my day without being bothered, but I know I can be engaging too when I want to. I mean, I get along with plenty of people, right? I don't have trouble making friends among all kinds of groups, and I can even be good at the small talk when I'm feeling into it and upbeat.

Is it really wrong for me to not feel that way all the time? I feel there's some sort of disconnect in me, in that I feel perfectly fine not interacting with people most of the time, but I also want to feel more stimulated and engaging more of the time. I think there's been some times recently when I've felt like I've come off as unnecessarily disengaged or uninterested when I didn't really mean to come off that way. Like once, I had gone out with this girl a few times and it had been great, but we went out for a drink and I droned on like it was an interview, and things have been BUH ever since. Or the other day, I had gone out and ran into a gay friend and a girl who straight up told me I was "beautiful" (this is pretty flattering, obviously), and all I could muster up was a "Oh haha, thanks" instead of getting any real conversation or anything. I wasn't really interested in either but I didn't mean to come off as dismissive like that!

Any help or tips?
