I went out in Southampton to the union club the week before then went for a quiet drink in the pub on my 21st.
I went out the day after and got into a scuffle though
But all in all, pretty tame. I couldn't justify the extra expense to do anything different and although my parents would have probably given me some cash to do something else, I didn't really want to ask because they've given me loads while I have been at uni.
