I did, because they were my only source of support at that time. I was starting high school and had no friends and got bullied a lot. It didn't help that I had a dysfunctional family either. I never went to the counselor's office and avoided telling others about my problems. It was because I was afraid of getting my parents involved, being kicked out of the house, and the wrath of certain relatives.
I noticed that younger people studying would get lots of attention at the meetings and if a person fitted into an existing group then they swiftly developed a social life
What nugget typed is so true, I remember being "love atmoic bombed" even though I was mildly interested. Sisters were giving me presents and bags of second hand clothes. I had 4 spiritual mothers who looked after me. The young people group invited me to places and gatherings. No matter how simple my comment was, I got praised for it. There was always a someone willing to give me a ride to the meetings, service, and to my house. I was assigned to a lot of householder parts for the school. Being around the witnesses at the love bombing phase felt so much better than being at home and school.
Of course, this all disappeared after I got baptized and became part of the R&F / college student instead of a pioneer.
Then one of the "in crowd" sisters managed get a Bible study and her young children to attend the Kingdom Hall. Instantly, they're love bombed and become celebrities in the congregation.
There were older Bible studies who attended, but they usually don't attract as much attention as the younger Bible studies. It was pretty sad watching them sit alone with only their Bible teachers and a few would go up and say hi to them.
