I was the age of 5, just a little boy

When my little sister had over a friend, and her name was Joy;
I remember they played barbie’s for just a little while;
And I of course was Super Man with my cape of towel;
After a while of bugging them they finally let me play;
I became the astronaut, all the rest of the day;
I flew out in my space ship to save the planet of two;
No matter how many enemies, because victory I knew;
With my space ship and I, not one did I miss;
Why, because every time I returned home,
 I got a heroes kiss.
