I have dreampt that I was at a boasting session or a$$embly, and that I did something stupid to get there and realized only after it was too late.
As for actually attending one, there would be very little reason to go. I might get up to date with the status of the congregation I used to go to. I might see myself how the building itself has changed (they built it into a double after I totally left). However, I might also be recaptured in the process. I might also be exposed to the witless family that brought me into the cancer and whose relatives wanted to host me. (Notably, that family has drained my energy every time I was with them, even for a few minutes.)
I already weighed the costs and benefits. The benefits are few (getting up to date with the congregation). However, the costs hugely outweigh the benefits. I will not be walking into a Kingdumb Hell again. Besides, I would rather go online and try to get updated that way--and I would rather be out of date on the congregation I used to attend.
