Wishing, I'm glad he's being nice, but please do not let your guard down. Generally, when they are nice, they are either up to something or are planning to do something. I'm not trying to rain on your parade, but I'm speaking from experience...these mlcers are very sly.
Oh, man, he's pouring on the woe is me and telling you about ow's mother. BTW, I'm sorry she's been diagnosed with that particular disease. I lost a good vet to that in September. To me, it's the long goodbye. I think it's interesting that he shared this info and told you about his cary needing repairs. Sounds like he's trying to play on your sympathies...don't take the bait.
All I can advise you to do is be vigilant when he's being overly nice.
Enjoy your weekend.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
