What did you come for?

Two children were sitting outside a clinic.
One of them, Joshua, starts to cry very loud.
“What’s wrong?” Akpos asked. “I came for a blood test” sobbed Joshua. “So why are you crying?” asked Akpos.
Joshua replied, “For blood test they have to cut my finger.” As soon as Akpos heard this, he immediately began crying profusely.
Astonished, Joshua asked Akpos, “Why are you crying, did you come for a blood test too?” Akpos replied sobbing, “No, I came for a urine test!”.
