All in a morning's work

This morning, while talking to my sister, I walked upstairs in a duplex to take care of 4 charming cats. The owners travel for work so I am at the house regularly. Telling my sister I will call her back, my greeting to the cats begins as I pick up their bowls. The place is pretty dark, and as I walk into the bedroom up pops the husband. A brief heart attack develops from the shock as  he says- 'don't be scared' (too late for that), 'I meant to e-mail you last night.'  Catching my breath and saying , "no problem", I continue to get the food bowls. At that point, still in the dark, he attempts to give me the new changes to the schedule. At this point it seemed  reasonable to point out that it is risky to assume I will remember this and I will e-mail him later. He gets up, which I assured him was not necessary, and he goes into the bathroom, I assume. Quickly finishing up the food and cleaning the litter box- I am out of there! This is not a unique encounter as schedules frequently get changed by clients that travel a lot. However they usually call out before I run into them , or I see their luggage. The 'surprise' element does not happen often- thank God- it is aging!
