Here is one memorable one --
It was one of those doors where you knock and then a voice inside the house calls out, "COME IN!!" At that time you look at your service partner and hesitate not knowing what to do and what necessarily awaits you if you do indeed decide to "come in." Perhaps thinking it was a case of mistaken identity, my service partner, an elder, knocked again and said (not sang), "We're Jehovah's Witnesses!". And again the voice called out, "COME IN! I CAN'T COME TO THE DOOR RIGHT NOW!" My partner looked at me and I could tell that, having not been shooed away at the admission that we were JW's, he was very eager for the potential Bible Study.
When we entered the house into the living room we were faced with the sight of a morbibly obese women spread out on a dingy day bed. Being a Star Wars geek I immediately thought about the similarities between this woman and Jabba the Hutt, spread out upon his dias. She was wearing a thread-bare mumu of sorts and I was startled to see her nipple poking out through a hole in the garment. It was one of those things you didn't want to look at but couldn't help but to look at. Just as she hadn't moved to answer the door, the feeling was that quite possibly she never moved from her birth, not for baths or even to use the bathroom. I secretly wondered what purpose the fly-covered bucket by daybed might serve.
Because the bed took up the majority of the living room there was no where for us to sit so we simply stood before her and my partner introduced us. The woman began to explain that she was a jehovah witness and my elder partner took some time trying to discern if she was simply a one-time Bible study that thought she was a JW, or perhaps a disfellowshipped one who the elders had lost track of.
We were then interrupted by a young teenager who excitedly barged in from the Kitchen saying, "Mama! Look I found some Kool-Aid!" He held up a wrinkled packet of cherry Kool-Aid. I assumed the reason for his excitement was that he was happy to have something to drink. I was quite surprised when he then said, "I'm going go dye my hair!" He turned and went down the hall with Mama yelling out for him not to color his hair with the cherry Kool-Aid.
