Losing a pet is never easy. Which is why we’re currently melting over this letter that a teacher got from her student after the passing of her beloved dog.

The letter was shared by a woman in Scotland named Lucie Dunne, whose mom works as a teacher — presumably at an elementary school. According to Lucie, Mrs. Dunne was worried about going back to work after having to put her dog, Charlie, to sleep. But she got support from an unlikely place — a student named Callum.

Not only did Callum write beautiful letter, but he managed to do it in an acrostic. In case you don’t remember from way back when, an acrostic is where the first letter in every sentence spells out a word when you look at it vertically. Acrostic poetry is extra special since it helps the writer focus on the topic at hand. For Callum, his words spelled out “Charlie.”

While Callum used words like “cheeky,” “happy,” and “adorable” to describe Mrs. Dunne’s beloved dog, our favorite was the R, for “relative.” “I bet your dog was really related to you,” he wrote.

Cue the tears.

The card went viral, and dog lovers all over Twitter got emotional.

We’re confident that the heartfelt letter made Mrs. Dunne’s day. Charlie sounds like he was a very good doggo, and he won’t be forgotten.
