Jo. I vote for Ellie's suggestion. When you tell Andy, do not sound like your D4 is in any imediate physical danger but that kind of language is something you do not like and think your D4 should not hear.
I like taking pictures idea too. If you do take/snap pictures, do it at a distance. Some of the thugs I worked with would get physical if you went up to one and took/snap a picture close up.
