What makes a buzz so enjoyable?

I’m not a big drinker, every once in a while I drink yet I can never understand what makes a “buzz” so enjoyable, I’m a little more social but the thing I notice most is how damn lightheaded I get. I just feel light and out of it. I’ve been drunk and I understand why people enjoy that, but I’m yet to understand why people enjoy a little buzz. I would love to hear how a buzz makes you guys feel?
