In a nice house in New York, lived a happy family. A married couple lived there with three children. The oldest child was Steve Rogers. he was 12 years of age and was quite small for his age. the middle child was a girl named April, with hair as dark as night. she was 11 at the time.
The youngest child was a young girl with plenty of potential. she was small and always had a smile on her face. she had long brown hair and gorgeous blue eyes. her name is Katrina.
The three children were alway content and well.
The roger family wanted to go to a trip to France. they planned and prepared. they were all so excited to leave. they left and they did enjoy the first few days.
On the 7th day of their trip with still a week left of holidays, Katrina decide that she was old enough to spend the day alone. her parents didn't argue with her. she left the hotel at 3:26 in the afternoon to walk the streets.
She saw many amazing stores with happy people. But when it was getting near the end of her walk, she noticed a man with black hair standing against the wall.
Katrina went up to the man and said, "sir, why aren't you smiling?"
The man looked at her with his green eyes and said "I am simply just not happy."
Katrina looked at the man confused. How could he be here and not be happy?
"Maybe your unhappy because your alone." said the young girl.
"Well, I'm not alone. you're here." he pointed out.
"Well, we should be friends so your not sad." She said.
The man smiled and crouched down to her. "ill just take you up on that offer." he grabbed her arm and waved his right arm over her arm. a wonderful tattoo of blue outlined flowers and patterns appeared.
"It's so ill alway know where you are, friend." he said.
