Overheard Conversations

I hate it when I overhear the end of a conversation without hearing the start. Today, in Wilkinson's, I heard someone saying (loudly in case you think I was eavesdropping) "...of course, if you turn it upside down so that it drains out all the water and then let it dry out it should work fine.." I'm just baffled as to what they were taking about.
