This is so true .  Any relationship worth sharing is going to have ups and downs....sunny days and funtimes and clouds and problems to be solved.    The difference is are you going to toss up your hands, say this is to hard and walk away. Or pull out your umbrella, take steps needed and make your way through the storm.   If it is worth it, you will  walk into the wind, let the rain spill down your face and keep  on moving until you reach the sun again.
