On Sunday, March 6, it was Mother's Day in the U.K.
Like many of her nearly 7 million Twitter followers, Rowling's mother is no longer with her.
The author's mother passed away in 1990 at the age of 45 from multiple sclerosis (MS). Sadly, her mom never even knew about her Harry Potter idea, because she kept her writing very secretive and only started writing the books six months prior to her mom's death, as The Telegraph points out.
It is something she said she regrets, but has since gone on to start a foundation in her mother's honor called the Anne Rowling Clinic.
Although her mom is no longer with her, Rowling still reminded the world that every mom is still with us and left this important message:
That's when her followers began Tweeting her back about their own moms passing away.
Being the super Twitter mom that Rowling is, she started passing out some touching thoughts of positivity and love their way to help them with their pain.
One person's mom is also suffering from MS. Thanks to Rowling, she has been able to have experimental treatment.
The conversation resonated with other followers, who were also thankful for Rowling's contributions on behalf of her mom, which moved her to tears.
Hold on, we're getting a bit teary eyed, too.
Excuse us while we go call our moms, and thank you to all those who continue to make strides against MS.
