As to the inevitable running into him while in his town. You perhaps should treat it as we are advised to treat our child tantrumming for a treat while out; always be ready to just turn and leave, abandoning a cart full of groceries if necessary. Do not be on tenterhooks always glancing over your shoulder and around corners, unless you really find that fun. Just go about your business with the relaxed attitude that if you have to come back later or go somewhere else to get something, then that is OK. Don't worry about confusing him or him making a scene. That is for him to deal with, not you.
