['I just celebrated my 35th wedding anniversary and I have never been happier in my marriage!', 'That is amazing!  So many people do not stay married these days, you should be proud of that accomplishment!', 'I am,  but I have to attribute most of it to my wife putting up with me for so long.  She is a saint!']
It's 100% for both of you!  It takes two to tango you know - Congrats on 35 years!
