Good Things About Being Three

You're small enough for a piggyback... from an eight-year-old cousin. 

Playing with fountains is genuinely thrilling

And even if there are two of you, you only need to bring one towel. 

 If people annoy you, you can just turn around and run away.

And if you get bored, you just flip yourself upside down and wait for the moment to pass

 You still think that Hello Kitty make a sweet pair of shades

You can take an excursion on a rocking horse very very seriously.  

And yet 'kiss the horsey, sweetheart, kiss the horsey!' seems like a perfectly rational modelling direction.

Most importantly, though, you can see cousins who you don't remember at all and go from almost-strangers ....

...through curiosity....

 ... to friendship....

...to co-conspirators, all in less than a minute.

Long may Three continue.
