The awkward moment when someone waves to you so you wave back, but then later you realize that they were waving to the person behind you. Or, the awkward moment when someone says "Hello!" and you say "Good, thanks!"

It's these awkward moments that get our faces red and haunt us in our memories. As it turns out, celebrities also fall victim to these toe-curling moments, and they have the pictures to prove it.

Kim Soo Hyun, currently the hottest young actor in Korea for his role in 'The Moon that Embraces the Sun', had such a moment in a fan signing event. At an event for sports brand Prospecs, Kim Soo Hyun was seen signing a card for a female fan. As he handed the card back to her, he reached out his hand to give her a handshake. For whatever reason, the fan failed to see the gesture and turned away, leaving Kim Soo Hyun hanging in mid air. He quickly made a fist with his lonely hand and sat back down.

Netizens who saw these hilarious photos uploaded comments such as, "That fan just made the single biggest mistake of her life" , "So funny! That expression in the last picture really sums it up" and, "I wonder how she will react when she realizes that she missed her opportunity".
