I do know what you mean Karrienz and have felt very similar emotions. So much so, that in the binder where I keep all my BMD certificates I have posted a poem in the front sheet which says this beautifully, and gives me a little lump in the throat whenever I read it. I don't know whether or not you know it, but it's by a late Victorian poet called Ernest Dowson. It reads:
They are not long, The weeping and the laughter, Love and desire and hate. I think they have no portion in us after We pass the gate.
They are not long, The days of wine and roses, Out of a misty dream Our path emerges for a while, Then closes.....
As you can see, it's the source of a well known saying. But it really does give pause to think about how short and, if we're lucky, sweet it all is.
