Whats in a phrase?

I have been with my husband Nick for 18 years, married for 12 of them. I suppose it was inevitable that I would take for granted how special he is to me. This was evident recently when I was explaning to someone who didn't know me or my husband why I hadn't done something. I mentioned that Nick had not felt it was necessary at the time to do it. This person then said the words "You should have married better." I was stunned, maybe I had mis-heard. It was whispered not shouted and I don't even know if they realised they said it. I quickly spouted some good things about my husband as if I had to justify my choice. I later felt silly and childish. If it had been Nick he would have pounced with a cutting remark or phrase that would have put them in their place. They would have realised that he lives his life never cowtowing to anyone or justifying his choices. As time went on I got more angry at myself mainly for not having a quick enough wit to respond. I then realised that this person had done me a favour because they made me appreciate Nick in my life and what he has and is doing for me. There isn't a day that goes by that he doesn't make me smile. A smile you may smirk, but having the ability to smile and laugh in your life is precious. We have been to hell and back and Nick has seen me near my end. Yet he has stood by me all the way. I love him more each day and thank my lucky stars the day he walked into my life. Shame on that person for judging without knowing and shame on me for not appreciating what I have and how special it is.
