As a parent, there is little more awe-inspiring than seeing the world through the eyes of your little one.
Whether it's their first brush with nature or their initial exposure to modern technology, a child's sense of wonder can often do much to restore a busy mum's flagging equilibrium.
So, it's perhaps no surprise that footage of a toddler seeing his first set of automatic doors has struck a chord with internet users worldwide in recent days.
The short clip, which was uploaded to YouTube on Monday, has gotten more than one million hits as members of the public join in one toddler's delight at the wonders contained within one's local grocery store.
Take a look at this and try not to smile!
