Four Letter Word

It's just a small four letter word With a meaning oh so deep You can feel it when your wide awake Or when your sound asleep Sometimes it makes you jump for joy Sometimes it makes you sad You can feel it when a baby's born Or for your Mom and Dad For your brothers and your sisters For that old dog in the yard For your Grandma and your Grandpa When you get a birthday card For that person standing by your side On the day you say I do For the children that you have in life It turns cloudy skies to blue I can't explain just what it means Must have come from up above It's just a small four letter word That we all know as "Love"
