Treacly Mother's Day sentiments be gone.

To promote her new humor book, "How Not To Calm Your Child On An Airplane," writer and comedian Johanna Stein asked a group of children what they've always wanted to say to their moms -- and compiled their hilariously honest answers.

"Thanks for using me as an excuse to get out of social obligations," one youngster answered. Oof.

"I wanted to shoot a rebuttal to all those sappy, marketing videos that seem to show up around Mother's Day," Stein told The Huffington Post. "Don’t get me wrong -- those sappy videos make me cry harder than anyone on the planet. In fact, that’s probably why I felt the need to make fun of them. So I could get back at those folks for making my eyes so puffy."
