I used to be involved with the biggest, lovingest, happiest bunch of social misfits ever. (Not all, please don't be offended if you are in that subset of this group.) Who? Folkdancers. Folk dancers and folk musicians seem to self-select for people who need social contact and are not very good verbally. You don't need any talent, just find a dance (contra, old English, old time, Irish, etc) and show up early. There is almost always easy to follow lessons for free. You will never get so many smiles and hugs in those few hours in years of the rest of your life. It is very child friendly. You can bring your partner, or not, it really does not matter. It is great exercise.

(gee. I almost have myself talked into getting back into it.)
