My first encounter with the guy outside the Co-Op came as I glanced at the near-carpet of betting slips, three smashed up paintings, and destroyed chair on the way into the shop. Unprompted and apropos of nothing, he made an extremely explicit sexual remark. So I would suggest that
TulseBoy made a pretty accurate reading of his friendliness or lack thereof, and equally that it is perfectly reasonable to ask the question on a forum about local community happenings.
Perhaps,
Nanker Phelge, you might be kind enough to let us in on the secret of what the guy is up to and how long he might plan to hang around. I can't say I'm feeling particularly comfortable about passing him now.
