Ticks!

Luckily for Lauren she rolled into a bush which broke her fall. Vanessa couldn't help but snicker at the sight of her haughty sister dangling gracelessly in a bush. Lauren struggled to pull herself free, then angrily tromped up the hill and rejoined her sister. She was dirty, but unharmed. Except Vanessa noticed something.

"Oh no Lauren!" Vanessa called out.

"What?" Lauren asked, confused.

"Look!"

Lauren looked down. There, on her shirt, were the tiny but unmistakable forms of three ticks!

"Ahh!" Lauren squealed, batting them off herself.

"This is bad!" Vanessa said. "Tick's carry dangerous diseases! They must have been in the bush, who know how many are on you!"

"W... what do we do?!" Lauren squealed. She hated bugs, and was terrified of the idea of a tick burrowing into her skin.

"We have to check you for ticks..." Vanessa explained.
