Re: your son-in-law, I don’t envy his predicament. What should be a pleasant experience and routine flights, going to help his mom, seems to be turning to a nightmare. My prayers are with him and I hope all goes well and ends well. The greatest pleasures I’ve received in life have been helping others who are trying to help themselves and just needed a little helping hand. OTOH, I’ve never put a nickel into the hat of a person holding a “I’m hungry” sign while sitting on the curb.
Sounds like you have a winner in your son-in-law!
