Poor grampa!!

One day at school the teacher asks that everybody brings for the next class an example of things you can find in a first-aid kit. The next day she asks each student what they brought.

- "Lucy, what did u bring?"

-"I brought band-aids."

- Very good! Who gave them to you?"

-"My mother."

-"And what did she said?"

-"That band-aids were used to cover up cuts."

-"Very good. Now, George. What did you bring?"

-"I brought alcohol."

-"Who gave it to you?"

-"My father."

-"What did he said about it?"

-"That it was used to disinfect wounds."

-"Well done! Pepito, it's your turn. What did u bring?"

-"I brought an oxygen tank."

-"Impressive! Who gave it to you?"-the teacher is really amazed.

-"My grampa!"

-"And what did he said about it?" 

 Pepito looks at her and answers in a raspy voice:

-"Pleaseeee, don't take it!!!!"
