Very good, Little Robin. That is the first verse of the song by Wingate and Petrie.
Second verse:
Next day two little maids, each other miss,
Quarrels are soon made up, sealed with a kiss,
Then hand in hand again, happy they go,
Friends all through life to be, they love each other so.
Soon school days pass away, sorrows and bliss,
But love remembers yet, quarrels and kiss.
In sweet dreams of childhood, we hear them cry,
"You can't play in my yard," and the old reply:

"You can't play in our yard," etc.
