not be a ham on this thread too
but here is mine in a nutshell:
I had a mix of worldly and JW friends. All of my really close friends were not Witnesses including my best friends. First best friend to age 10 was Gary Monk. My sister Vangie was best friends with his sister Colleen. They were a nice Catholic family. He was a great kid best friend. Via him, I saw that he got to celebrate Christmas etc. and saw a bit what it was like. The only thing I was a bit jealous of was not getting to be in Boy Scouts with him.
He moved away and Lee Kinney moved behind me and we became best friends and still are, though he still lives in New Mexico.
All of my friends in school were not JWs. I didn't celebrate holidays, salute the flag, drink, smoke, have sex or date (until H.S.) but despite that my dad was the presiding overseer and literally had built the congregation, I was permitted to play little league, participate in the spelling bees, science fairs, etc. as a kid. When I got older during my teen years, my dad went inactive for a decade which worked out perfectly as I was totally free to continue sports, lettered in three sports Junior high and two varsity, do clubs, honor society, I planned and decorated our Prom, and went to both Junior and Senior proms (junior I went stag and had a great time, Senior I went with this totally new babe who moved to town but it was a nightmare), went to school Dances, did I mention that I played football on the Artesia High School (STate CHAMPIONS!!) team :-), went to a few parties, on camping trips with the A-Club (athletic club), was a Lion's Club 'Boy of the Month" and spoke to them at their lodge, etc. etc. anything that I wanted to do I could do as a teen. I also stayed out as late as I want and was at home whenever I wanted.
I was never made to go in service, join the ministry school or attend meetings but I did go to meetings as much as I wanted and usually tried to take my mother.
Out of choice, I didn't drink, smoke, use drugs etc.
I did have several "puppy loves" who were JW girls but I never got to have any fun with them being a good JW in that way. The one "relationship" was squashed not long after it started and that sort of set a pattern with all the good JW moms running interference the rest of my teenhood. I was very shy and stupid then so I never followed-up on any worldly girls that liked me but I dated a couple in high-school and took one to homecoming.
I was always between two worlds. Considered an outsider and goody-goody by my non-JW friends/classmates and considered too "worldly" by the JWs.
I believe that the biggest factor, next to the liberality of the parents, as to whether a JW forms non-JW friendships is whether or not their are any JW peers in the congregation and how well they get along with the JW or how they treat him or her.
As for me in my small hometown, (luckily perhaps) there were virtually no JWs of the same age or in my class. All the JW kids were either a few years older or a few years younger than me. Thus it was pretty natural and easy to have non-JW friends and NOT be close to the JW kids in my congregation or that I knew.
Also, if there HAD been JWs who were my own age, if they had treated me as lower class (since we were quite poor) or in some way mistreated me like kids sometimes do, I would not have been friends with them. That's why I say it depends on how the JWs treat each other. I think girls especially can be petty and mistreat eachother when they are young or teens and get jealous, etc. thus leading JW youths to seek friendships elsewhere.
that's all from me
