Hi, Kevin, long time no see! Welcome back and thank you very much for your perfect answer! I'm glad you came back here again - I really like to enjoy your posts (informative but readable). Actually, I (maybe not only I) was hoping you would appear and continue to post - a dream come true now!
As for my query, you answered it with the key word 'distance' - distance in time, distance in a relationship. Yes, it's quite understandable. And I'd like to add one more 'distance' - 'distance' in the extent of politeness and certainty.
