I'm 20 and have been drinking since I was 17. At my current workplace I am the youngest and everyone likes to hang out and go to the bar and I can never come because I'm too young. They often lament about how they wish I could join them too. Also when I want to go on dates with people they often suggest a bar and I feel embarrassed because I can't go and it makes me think they won't want to date me. When I lived in Europe briefly going to the bar was the best and I had a great time. I have had no problems with alcohol and I think 18 is a fine age for it to be manageable. 21 is just ridiculous. In Europe they have more flexible drinking ages but stricter driving laws which just makes much more sense.
I have 41 more days until I can go into a bar and I'm so tired of waiting. I don't envy anyone else going through what I'm going through
