On Edric Tucker's first day of school, he posed for a photo [1], like so many other kids, with a chalkboard that read "First Day of Pre-K." However, Edric's photo is different than most children's in that his mom, Katie, is photobombing him — but for good reason. The photo, which was posted to Instagram by Edric's dad, Scott, also highlights the fact that it's Katie's first day of school [2] — dental school, that is — or more specifically, 22nd grade. The dad also shared the photo on Reddit [3] with the sweet caption: "Wife starts dental school today, son is glad to have a school buddy."
