How to remember the good times in your marriage
One word: Gmail. Yes, Gmail remembers everything. It captures all your emotions in the form of conversations. In general, when you get separated or divorced, only the nasty bits linger in your brain. Recently, I was searching my Gmail for when a particular event I attended occurred. Much to my amazement, an email thread between The Ex and I popped up. It was laced with nice words from the Red Queen. I won't post it here because I might blush. But, finding actual dialogue from years ago that isn't just another ass reaming made up of bits and bytes was very refreshing.
So in conclusion, if you don't currently have a Gmail account, get one. You never know when you may need some words of encouragement from someone who hates your guts.
