I just want to greet all the moms in the world a Happy Mother’s Day! (At least, it already IS on my part of the world.)
Now, Mama, Mom, Mother… It’s still quite subjective. She may be the one who gave you birth, or the one who brought you up. She can also be grandma, or auntie, or your eldest sister. Biological, or adoptive. Whoever your Mom is, and how ever the circumstances were that she became your mother, she deserves this greeting.
God bless you!
