Slip 'N' slide

"Look!" Kara excitedly shouted.

Her Mother has just finished getting a Slip N Slide put together. A long stretch of rubber or plastic, with a tunnel spewing water down like a curtain at the end. The others rushed to get their bathing suits, but Lauren was the odd one out.

"Why aren't you joining them, dear?" Kara's Mother asks.

"I didn't bring a bathing suit." Lauren said, bashfully.

"Oh, don't worry." Kara's Mother said, waving away the complication.

Lauren felt relieved for the first time all day. Until...

"I keep this for emergencies in case I forget Kara's swimsuit. It should be able to fit you." Kara's Mother said, smiling.

Lauren's hopes were dashed when she saw what Kara's Mother took out of her purse and unfolded.
