He was searching for new adventures. He's probably tired of his wife. Drinking that much also shows that he was hiding some weaknesses.
Nah, it was his 'regular show' for over 20 years.
His lady wife (still going strong btw!
) was/is what you may call 'some kind-a-woman' as well, never blinked an eye about his escapades, always let him back in. Perhaps the fact of HER being the one who brought in the daily cash was/is a major factor there too. I've often asked myself why she didn't kick his butt, but I guess it was 'true love' indeed!
I can well see the two of them grow old together, and isn't that very nice indeed?
