Wow, where to start. First of all, it’s pretty clear this person “have had rough day”—they obviously suffered an injury, possibly to their brain. Our best guess is that they’re trying to say “You know you’ve had a rough day when you step on something painful with your bare foot and can’t muster the energy to look down to see what it is—let alone pick it off—and instead just glumly hope it dislodges itself by your next step.” It’s a lot for a card. Which is why we'll generously assume the author wanted to save space by leaving out a word, using "to" instead of "too," and inexplicably switching from “you” to “u.” And we have no idea why they chose this picture. Maybe they were angling for a “horses injure their legs and have to be shot” kind of thing? At any rate, whoever this poor soul is should probably stop punishing their kids for leaving their legos on the floor by making them write someecards explaining their pain. 2 out of 10.
