Tom and Timothy were in the same regiment in the army. They were inseparable
friends and spent their evenings drinking together. After retirement, they went to
different states and settled. However, they kept correspondence through letters and e-mails. To keep the memory of their boozing bouts alive, Tom always filled two glasses
with rum and water and sipped from each alternately! When somebody asked him
why he did so, he explained: “This glass is Timothy’s; this one is mine. So I take a sip
from each – one on behalf of Timothy, the other for myself.” Suddenly one evening
Tom was seen with only one glass on his table. He was asked what had happened. He
replied, “You see, I have given up drinking but Timothy has written that he has not. So
I have put away my glass and drink only on behalf of my friend.”
