Prom was absolutely forbidden in my congregation. My older sister went because her best friend was on prom court. Both of them were JW's. My parents were really upset by it, but my sister's friend's grandmother, with whom she lived and who also was a JW, was completely in support of it. The elders in my congregation found out about it afterwards and everyone got talked to. So by the time it was my turn for prom, there was no chance in hell that I was going.
I snuck out to my homecoming dance my junior year in high school and my mom figured it out and actually came to my dance, walked right into the middle of the dance floor where I was, and dragged me out of there. As you can imagine it was a devastating and humiliating experience for a teenager of 16 who is already having a hard time fitting in because of her religious differences.
Actually when I got home that night (because I got in a huge fight with my mom and refused to go home with her; she only finally left because I promised to come straight home, which I did NOT do, I was so angry!) there was this letter in my bedroom from my mom that said all kinds of nasty things, that she didn't know who I was, that she couldn't believe how deceiving and manipulative and conniving I was, that she didn't know what she did wrong as a parent to have her daughter turn out this way, that she could never trust me again, that I clearly lied to everyone about who I was when I got baptized...it was devastating to read it and still stings when I think about it.
