An Arab needed a heart transplant, but prior to the surgery the doctors needed to store his blood on standby. As the Arab had a very rare type of blood, it couldn't be found locally.
So the call went out to a number of countries. Finally, a Sindhi was located who had a similar type of blood.
The Sindhi willingly donated his blood for the Arab. After the surgery the Arab sent the Sindhi as a token of his appreciation a new Rolls, diamonds, Bulgari jewellery, and a million US dollars.
Once again the Arab had to go through a corrective surgery. His doctor telephoned the Sindhi who was more than happy to donate his blood again.
After the second surgery, the Arab sent the Sindhi a thank you card and a jar of almond halwa.
The Sindhi was shocked to see that the Arab this time did not reciprocate the Sindhi's kind gesture as he had anticipated. He phoned the Arab and asked him why he had expressed his appreciation in not so generous manner.
The Arab replied "Chariya...now I have Sindhi blood in my veins !"
