On my last trip to Kiev(the capital of Ukraine), I was a witness of a very funny tickle. This particular tickling opportunity presents itself all the time in Ukranian subways. The subway there often becomes very crowded. During rush hour the commuters push each against one another to allow the maxinum number of commuters onto the train. The result is that people's bodies are pressed so tightly against one another that one can barely move. Anyway, I was waiting for a train. As the train came to a stop I saw a boy and a girl together. They were probably in their early 20s. They were pressed tightly together as previously mentioned. Somehow the girl managed to get a firm grip on the guys ribs and she really dug her claws into him. He was laughing hysterically and his body was shaking all over the place....well it would have been if they were not so tightly packed together. Well, then the door opened and he came running out to get away from her. She and a couple of her friends came out laughing at his reaction and they went up the esculator together. No, he did not tickle her back...at least not while they were in my view.
