Watch: Family deliberately gives kid terrible gift to test his manners

You can imagine all the things a three-year-old might want for his birthday -- action figures, stuffed animals, blocks. Heck, even some candy would be nice. But an avocado? Probably not too high on the list.

Despite his certain disappointment, this adorable little boy managed to hide his lack of enthusiasm when his family gifted him the fruit (yes, it's technically a fruit).

Henry, the New England native featured in this now-viral Vine, not only smiles when the wrapping is removed, he actually says "thank you." Though he quickly sets it aside rather than examining it further -- because what do you do with an avocado, really?

Kudos to his parents for doing something right.

According to the New York Daily News, the video was posted earlier this month by the boy's uncle, Jeff Simmons, who captioned it, "When you are really good at pretending to like your birthday gifts."

Henry's mom, Victoria Simmons, told the Daily News that her son opened the "present" a few days before his birthday. She said it was meant as a test to ensure the boy knew how to receive a gift, even one he didn't like.

“It was the first time he could open gifts and recognize on his own what they were,” his mom told the outlet. “We were concerned he would open the gifts and be really honest like he usually is.”

Not only was the boy gracious during his trial run with the avocado and other items they tested him on -- including a K-cup and an oven mitt -- he did great on his actual birthday.

So what was his real favorite present from his big day? According to the Daily News, his favorite gift was a monster truck.

“He’s obsessed,” his mother told the Daily News. “He sleeps with them.”
