Should I be concerned?

As I've been running around with my adorable niece Sydney and nephew Holden in NY, I've had a concerning realization.

There is little difference between me and my 4 year-old niece. Sure we're both girls and related but it goes a lot further than that...

Evidence:

• Favorite song: Party in the USA
• Favorite ice cream flavor: Pink Bubble Gum
• Favorite activities: swinging, painting our nails, and reading books
  
• Favorite outfit: "twirly" dresses
• Favorite movie: High School Music (see pic above)
  
• Favorite shoes: flower sandals
• Favorite color: pink
• Favorite hair style: braids
• Favorite person: my mom
• Favorite breakfast: crepes
• Favorite lunch: pizza
• Favorite dinner: roast with mashed potatoes and rolls
• Favorite weather: rain
• Favorite bedtime story: Harvey Potter's Balloon Farm

Is this an abnormal amount of similarities between a 22 year-old and a 4 year-old?
Absolutely.

Am I concerned? No. Not really.
