Atty, nobody needs to have a theme! We talked about before. We can have a nice turning party WITHOUT a theme. They just need to be present on PVT at the time of their turning--we provide conversation, flowers, cupcakes, balloons and fireworks.
We've done many threads and parties without a theme before.... A theme is extra (and it's a relatively new addition to our celebrations).
Even I thought avatar parties had to have a theme. 'cuz.... what do you put in the avatar otherwise?
The rant was not directed at you, caused by you, nor is it a bad question. It's just.....the answer is....not well defined.
