Do you know how you can tell how long a missionary has been "in the field"?
The 1st year, she finds a fly in her water glass, and pours the whole thing out.
The 2nd year, she finds a fly in her water glass, picks it out, shrugs, and drinks the water.
The 3rd year, she finds a fly in her water glass, smiles, and says, "Oh good! Soup!"
