Living with Bob and "Al"

Most of the time Bob is silent, nodding his head from time to time as if he agrees with what Sheri is saying , even if  "Al" clearly does not understand. But last night Bob was trying very hard to relay something that had happened at "work" (code for Adult Day Center), but the story was so mixed up and repetitive , Sheri could not make heads or tails out of the conversation. She did gather though, that someone was in distress and "Al" tried to help.
Dear sweet man.
