This is what I did:
My 21st fell on a Sunday.
That Friday night, I went to a local restaurant that serves really good drinks. Had all my friends come with me including those who are underage. One of the waitresses is in my chapter so she served me (although I was one day away from my 21st
). That Saturday night, my friends and I who were of legal age all went downtown to the 21 and up spots. The bouncers didn't give me a hard time luckily. It was 11pm and I was going to be officially 21 in an hour so they didn't make a big deal out of it.
