Common ailments

“Could you help your dad in the yard cleanup?”
“I would like to but I really don’t feel well."
"Why! What happened?"
"I have a headache.”
“Where is the headache?”
“It’s all around the head, and it gets worse when I shake my head. I feel like my head is spinning.”
“When did it start?”
“About, just now.”
“Quite convenient!”
“Why do I have headaches like that? This is not the first time. I mean it could be serious?”
“Ahh! I don't think these are serious, in fact these are quite common. Unhelpful kids are usually the ones affected. They seem to get better with age.”
