Whoever said love is blind had no idea how truly powerful that expression can really be.

Redditor mack3r posted this photo of Valentine's Day cards made by his blind daughter, who's in second grade.

The cards were written in braille. The words on the card matches the words in braille.

It's a simple, yet wonderfully poignant gesture.

The cards were a huge hit and spurred a conversation on Reddit about how people can write braille, as well as a litany of comments about how wonderful this was.

It's safe to say this girl -- and her classmates -- are going to have a Valentine's Day they won't soon forget.
