This happened a couple of years ago and was right before I could buy alcohol – just a few months shy. I was at a huge party and had already gotten a few glasses of punch. I was feeling just a bit tipsy but after an hour or two, I was feeling thirsty again. I remember thinking another beer would have been so, so good.
There was only one person with alcohol at the party: a guy, who was slightly older. He was one of the few there old enough to buy beer and had brought a 12-pack, but that mostly for himself and his friends. I didn’t know him at all, all I knew was that he had around six beer left and I wasn’t the only one who was thirsty. The stores were closed at this hour, so even the few people who could buy beer, well, couldn’t.
I didn’t really know how to ask for a beer and didn’t want to be “that” girl, so I just thought I would chat him up until he offered me something to drink. It worked. Flirted with him, smiled at it, showed a lot of interest. Then I subtly moved the topic to how I was still 20 and not old enough to buy beer, but I would in a few months.
