That's so cool that you're able to enjoy Girl Scouts. Sorry about the problem knocking on doors, but I understand!
When I was still a door-knockin' JW, I also went with my girls on their school fundraisers and experienced extreme anxiety because door-knocking in my mind was ONLY for the kingdom work. I guess that was in your mind too and that's why cookie time caused some anxiety in you.
Now I just hate fundraisers all together. I don't think it has anything to do with my JW background though, most parents are sick of 'em, especially if you have more than one kid in more than one activity.
