Lucy was outside playing with her new kitten.  She was having such a fun time that she forgot about being gentle with the kitten and she accidentally pulled his tail.  That kitten did not like to have his tail pulled and he scratched Lucy right on her arm.  Poor Lucy, she had a bad scrape and she needed a band aid.  She asked her mother to help her.  They got the band aid out of the box and carefully unwrapped it.  Then Lucy's mother gently cleaned her scrape and applied a little bit of ointment.  They peeled the paper off the back of the band aid and gently applied it to the scrape.  Lucy knew that it was important to keep the band aid on for a few days until the scrape started to heal.  After the band aid was on and she got a hug from her mother Lucy felt so much better!
