It doesn't sound that long, when you say "two" out loud. What's two years worth? For my son, born the day after Owen passed, it's a lifetime. Maybe it's like the old adage, the one that goes "how heavy is a glass of water"? It's something that doesn't sound so big when you say it out loud, until you've lived it.
Owen lived life big. He would pack more in two years than many would in two lifetimes. He taught me so much about expanding my horizons and tastes. I had my first sushi with Owen (white tuna on rice). I drink Blue Moon beer (I don't normally care to drink at all). He taught me to live a little, which was a lot for me.
Maybe it will never be "ok", but maybe one day, when we're not looking, the happy memories will outweigh the sadness of not being able to create new ones with those we love. Maybe when we live our lives a little bigger, we make more space. Space to fill with the good things in life, and maybe they'll outnumber the sad things.
Maybe that's the whole point.
