Thank You, Mom
1 For all the times you've worried, For all the times you've cared, For all the times you've put me first, And all the things you've shared,
5 For being there when needed, For giving me your heart, For teaching me what's right and wrong, And making me so smart,
10 I thank you, Mom, for all you've done; I absolutely owe you one!
