A mosquito , feeling rather tired after a long flight, decided to stop and rest. She was a very conceited mosquito, and very fussy about where she rested. searching for a suitable place, she spied a bull in a nearby field.
Swooping down, the mosquito landed on top of the bull's left horn. She cleared her throat slightly and said :
" I hope I'm not too heavy for you sir. If I'm, I beg you to say so truthfully and you can be sure I'll be on my way."
" As you like, little girl !" answered the bull. "But the truth is, I didn't even realize you'd landed, so I certainly won't notice when you go."
