     My sister saw a lovely cup when we are shopping the other day. She liked it at once. Then

she bent down and picked up to look at a price on it. As she did this, lots of tea splashed on

his T-shirt! I had to try hardly not to laugh at her shocked face! My sister wanted get out of the

shop as fast as she could when a shop assistant came over to us. It was turned out to be her

own cup, that she'd left on the shelf by mistake. The assistant was clearly as embarrassing as

my sister, for I just thought it was funny!
