making tea for mother

A little girl made a cup of tea for her mother.
“I didn’t know you could make tea,” said Mom taking a sip.
“Yes. I boiled some water, added the tea leaves like you do, and then strained it into a cup. But I couldn’t find the strainer, so I used the fly swatter.”
“What!” exclaimed Mom, choking on her tea.
“Oh, don’t worry. I didn’t use the new fly swatter. I used the old one”.
