How you got a new boyfriend

A rather reticent young girl was asked how she got on with
her new boyfriend.
“Let’s just say my legs are my best friends,” she replied
mysteriously.
“Oh come on,” said her mate. “What does that mean?”
“It means he came on too strong so I walked home.”
A few weeks later the two friends were talking and the girl’s
mate asked her how her new date went on the previous
night.
“Pretty much as before,” she replied. “My legs are my best
friends.”
Time went by and on the third time they met up, the girl
looked radiantly happy.
“You’re looking well,” commented her mate. “Something’s
doing you good.”
“Oh yes,” replied the girl. “I’ve met this wonderful bloke and
let’s just say even the best of friends must part.”
