Valentines never sent

In 2015, Alexandra Petri, a Washington Post columnist, came up with some famous Valentines that were never sent, or even thought of.

Valentine from your dog:

Valentine, I love you! I also love this tree and this tree and this leg and this unidentifiable brown substance I found on the sidewalk and am licking and rolling in, but you I especially love!

From your cat:

Valentine, I am marginally less indifferent to you than I am to others.

From the NSA:

Valentine, I love listening to you talk.

From 'a young adult:''

"Baby, you are the only one in this dystopic world of blindly conforming adults who understands me."
