Gallstone and Pilonidal Cyst

My elder sister just had her gallbladder removed as there is a stone the size of olive inside. B2 is in the hospital to have his pilonidal cyst removed as well. I wonder if it is a coincident that both are the 2nd kid in the family. Poor B2 has been waiting in Tan Tock Seng Hospital since this afternoon. He is supposed to go in at 6pm but was still waiting outside the operating theatre at 9pm. My poor boy must be starving as he is not allowed to eat prior to surgery.
