A young woman was suffering badly from hay fever. She was going to a fancy dinner party that night and figured she would need at least two handkerchiefs to get her through the evening. She didn't have any pockets, so she stuffed them both in her bra. Halfway through the night, she had already used up one handkerchief and was rummaging around in her bra for the other one. She was having trouble finding it, and soon she noticed that everyone at the table was looking at her. "What on earth are you doing?" asked one of her colleagues. She replied, "I could have sworn I had two when I arrived!"
