You are the best one I know 
Yes, I know that you are my hubby's mom 
But to me you are like my mom 
So good to take things in your stride 
So good that you stay strong 
I have learned so much from you 
And I know that you are so true 
Blessed to have a loving mom in law 
Yes as loving as you 
Wishing a very happy birthday to you! 
God bless you!
