Our former congregation was the most uptight, stick-up-the-butt kind of people you'd want to meet. So no, there's absolutely NOTHING to miss about the "get togethers". In fact, I despise the term "get together". They are so anal they can't even call it a party. (Because the word party is obviously synonymous with drugs, sex, and alcohol.) There was NEVER live music at any "get together" we ever went to. OK, once at a couple's going away "get together", we all had to sing 2 of their favorite Kingdom Melodies acapella. God, it was pathetic enough to have made the cover of a WT magazine! But in general, to learn a musical instrument would mean one would have to take a little time away from his bible reading and personal study, and you know what happens next! Apostacy for sure.
The "get togethers" we went to were indescribably lame. It was nothing different than the meaningless and transparent chit-chat we'd have to endure after every meeting. It was kinda funny to see the clothing people would choose to attend outdoor "get togethers". One incredibly anal elder would always wear a suit and tie. Although he might have taken off his jacket to play softball once. One elder probably didn't own tennis shoes or tshirts, because he came to an outdoor picnic with a long sleeve dress shirt, shorts, and black knee high socks and black dress shoes (and yes, his socks were pulled all the way up.)
