Thank you all for all the usefull information. He said he wants to meet for coffee on the aftrenoon if my work permits it. He has not mentioned anything about play, just talk. I know about the safety calls and I will do that for sure. I was thinking about taking a friend with me-to sit inconspiciously on the next table and just keep an eye out. I will see how he will react to the idea of safety calls and go from there.
Once again many thanks for the help and advice to all of you!
