A Scottish lad and lass were sitting together on a heathery hill in the Highlands. They had been silent for a while; then the lass said, "A penny for your thoughts." The lad was a bit abashed, but he finally said, "Well, I was thinkin' how nice it would be if ye'd give me a wee bit of a kiss." So she did so. But he again lapsed into a pensive mood which lasted long enough for the lass to ask him, "What arre ye thinkin' now?" To which the lad replied:

"Well, I was hopin' ye hadn't forgot the penny!"
