Growing up we entertained them everytime they came- Either for lunch or dinner. I got to see how these "servants" really took advantage of the world--travelling, fine dining, designer clothing. Heck they lived better than most the witnesses in the congregation.
I wouldn't say I regretted it at the time. But these were occasions for a reality check for me. I got to see first hand the hipocracy and how out of touch these people really are.
