I can ride a bike and hike a trail

You can build a sandcastle and swim safely with me

I will stick with you through thick and thin

You will need one or more of me to play hide and seek

I can catch a ball and score a goal

You can paddle a canoe, but it's easier with me

I can catch a firefly and climb a tree

You can go camping and count the stars with me!

Who am I?

Answer: A FRIEND!
