Redditor Trai-harder posted a picture of a birthday card drawn by an 11-year-old that basically nails the general timeline of any person's time on Earth. Look at how the baby's expression of wonder changes to the typical adult countenance of anguish. That's one sad stick figure. Oh, and happy birthday! You're almost dead!
The text reads, "Life is a waterslide where you die at the end…" while the artwork depicts a baby becoming a man, and then becoming an old man with a cane. The artist has added a helpful "You are here" arrow to indicate that the lucky recipient of the card is very near the end of the waterslide. This kid is too young to be this aware of the trajectory of human life.
There's no info in Trai-harder's post about the kid who drew the card, or the person who received this wise and depressing message from the elementary school Grim Reaper. At least in this version, life is a waterslide (wheeeeee!) and not, say, a hellish trek through a barren desert. That interpretive artwork will come in about 20 more years.
