They are so much fun, they are always dancing around, doing something crazy.
They fall over and trip all the time, and they act like it's no big deal.
They talk a ton but don't make much sense and you say "that's great honey" even though you don't have a clue what they are talking about.
They can go from laughing to crying in under a second.
They will randomly get naked and run through the house.
They need your help putting them to bed.
They will randomly give you hugs in the middle of a conversation and tell you they love you.
If you take their drink away from them, they freak out.
They will talk to anybody, doesn't matter if they've never met before.
Your needs are completely none of their concern.
