She sighs as she collapses on the sofa tonight The kids are in bed with just a night light But then she hears them giggle and then the patter of flight A bump from the wall and a little lady cries It's laughter and tears that fill up our lives It's joy and sorrow that binds us and ties Each tear into darkness and each smile into light It's laughter and tears that fill up our lives A scrape on the knee only a mother can fix The remedy is a Band-Aid, two hugs and a kiss A flat on the bicycle, daddy's got this Then it's off to kill dragons or make them our pets Cause this part is filled with laughter and tears The climbing up trees and falling down stairs The echo of joy on new year's midnight Where the soft lulling ocean drinks in the moonlight Mom, you don't understand you've never felt like i do Smiling she says i once was young too And heart's they break open and get torn in two But heaven holds the promise that makes all things new Cause this is the part with laughter and tears Of teenage disappointments and first driving fears The freedom of knowing the wrong from the right The pain of forgetting, the hurting inside Wife, i have loved you for all of my days Through all of the changes one thing has stayed The Love that we share will not wilt away What is planted on earth... will grow in heaven one day Cause this part is filled with laughter and tears The happy and sad, the hopes and the fears Her eyes run the mantle and fill up with tears As she sits by the fireplace and remembers the years
