In case you needed a reminder here's proof that the bond between mother and child is strong.

Watch as this man, who's been abroad for two years, comes home and surprises his mother. Clearly, she's stunned and her reaction defies description.

She falls to the floor and looks like she's fending off a ghost, but, hey, we all express joy in our own way, right?

Bottom line: that's a good son right there.
