This topic may have been an OP previously but I didn't get an opportunity to comment so here goes;
Mine are pretty simple;
The BEST day of my life:
It was the day I married my beautiful wife of 49 years. Yea we got married during the turbulent 60's. I was nearly 20 and she was an outstandingly beautiful 18 year old surfer girl. In fact she was THE sister that every young brothers in our southern California circuit wanted to have as a girl friend and I was the envy of every young brother. She and I were feverishly in love. I still love her feverishly today even though we often clash over ttatt. She accepts my stance and I accept hers (for now).
The WORST day(s) of my life is sort of a draw since there were 2:
1) That day in 1977 (10 years into our marriage) that she told me she was f**king another guy and left me and our 2 lovely children for several months-----to find herself; and 2) the day that ttatt really took hold!
However, as I look back at it now, the day that ttatt really took hold also proved to be the BEST days of my life!
Like to hear yours if you care to share.
