not your typical pnm

Ok basics: great grades and super involved in HS. Legacy.

The reason why I am a 20 year freshman is, I did 18 months of international missionary work. I wanted a break in between HS and college because I had no idea what to study and well I just wanted to do it. Anyway I grew up in the San Diago and to be honest I did not think I ever wanted to be in a sorority. Well in my program I met other girls my age were going to rush when we were done, women who had just graduated and even women in their 30s and 40s who wild/good/fun times were well insane (Imagine when social media could not prove anything and it just lasted on old school film). These women were from all over the USA and even Canada. Because of this recs are not a problem. All I heard was how great could be. My mind is changed. I just want to know if being a 20 year pledge is really weird? I like to go out, have fun, and I do realize I will be with 18 year olds. In fact I'm living in traditional freshman with a friend I met in the same boat. Any opinions are welcomed!!
