Yes, and when you go back, wear your ninja suit. By this I mean a decent pair of slacks, a long sleeve dress shirt, a tie and any kind of id that you can hang on a lanyard form your neck. Carry a clip board or a manila folder. Invariably they will think you are some kind of government functionary, often Social Services. If you wear a sports jacket, they will think you are a plain-clothes police. You don't have to (and should not) represent yourself as any one of these. Just have the chutzpa to walk in and snip off some cuttings.
