What is the best thing about having a sibling?

I never have to worry about anything I do or say in front of them. The worst and funniest accidents I've been in were with and caused by them. It's nice to watch your little siblings grow up, experience all their 'firsts', and get deep into their hobbies. Also, they used to do everything I told them to do, like make me food. mwahaha

OH! I'm waiting for nieces and nephews, I hear they're fun.

Inside jokes

Getting into trouble together and us vs. the parents mentality was fun too!

You can pick on them and have them do your work , that's what happened to me cuz I'm the youngest

Having a friend, and helper.

They make me laugh and we can make fun of our parents together

shopping with them, you can get discounts and second opinions before buying stuff

"buy two get something half off / free"

There is always somebody to talk to and fight with at times :)

You potentially have a lifelong friend.

Someone to count on :D
