Yes always did from day one, came in early and left late. I like meeting new people and socializing when I am sober. My active alcoholic self is the one who is a complete hermit.
Edited to add that it might be sometime awkward and intimidating in some meetings which are more "cliquish" still the time before and after meetings is really important to make connections which one day when you are close to picking up might be there.
If you feel shy, I'd suggest going early rather than staying late when people tend to yack with their friends and the good hearted "twelve steppers" seeing a newbie might not resist the urge to pounce at you with their big book LOL.
If you come in early, chances are that there will be only one or two people and you might ask them if you could help them set up for the meeting as an ice breaker.
so now you will know two people by name and instead of being just another newbie coming through the revolving door, to them you will be Ellie who is willing to help out.
