It seems Serena Williams could be about to start something genuinely awesome, a feel-good trend that’ll warm the internet’s collective heart.

The catalyst came this morning, when Serena shared this short — but pleasantly perfect — note to her unborn child.

My Dearest Baby, You gave me the strength I didn’t know I had. You taught me the true meaning of serenity and peace. I can't wait to meet you. I can't wait for you to join the players box next year. But most importantly, I am so happy to share being number one in the world with you…. once again today. On @alexisohanian bday. 😉 from the world's oldest number one to the world's youngest number one. -Your Mommy

Enter Annie Apple, the mother of Giants cornerback Eli, who was so inspired that she sent two heartfelt tweets of her own.
