I also feel that if W missed the inauguration WE would ALL understand!!! He is VERY CLOSE to his dad being in intensive care at his age IS NOT GOOD!!!! I would hate to see something happen to his dad while he was attending an inauguration I feel he NEEDS to stay by his dad!!!!
I finally understood when I was hospitalized for Chest Pains (false alarm) in 2010 and I was being bothered every 30 minutes with something, I was glad to get home for some rest.
So I believe H told W to go as the Bushs’ need to show the flag supporting the President and the country.
I don’t know if he is still coming but if they want to attend Trump should sent Trump Force One to pick him up so he arrives in time for ceramoney and send them home on Airforce One so ge can be with his parents
