A screen grab from the video.

Children are extremely adorable and very straightforward in their approach, unlike adults who have all kinds of biases. Toddlers in particular have no complexes, are very innocent, curious, and full of questions. They are very frank and hide no bad feelings. Yes, they throw tantrums, okay, but they are short-lived. They are back to their effusive self soon afterwards.

The tiny tots also perhaps make the world’s best public relations managers. They strike a chord with their as-open-and-friendly-as-you-can-get acts, as a toddler showed during a recent flight.

He walked down the aisle, and while doing so shook hands with every passenger whose seat flanked the passage. The passengers beamed at his innocent gesture and reciprocated his warm gesture. With the exception of one flyer, who did not respond, because he was fast asleep. The toddler, with his outstretched hand, waited for a while then walked away.

The video was shared by one user, Morissa Schwartz, with the legend ‘What a friendly soul.’ It bagged over 2 million views and more than 53,000 likes.

Twitterati reacted effusively to the boy’s move.

"Look at all the smiling faces this little angel made with just a sweet, earnest effort. We could all learn a lesson here," said one user.

"Awww! adorable," remarked another.

"Look how many smiles he created on that plane!" exclaimed yet another user.
