HAM radio: childish fun?

I can't stop thinking of this episode few days ago.

Once I fed breakfast to XXYL (2y4m old) I left her playing and went into the shack. YL was still sleeping. XXYL came over and joined me while I was listening to who was on the band. She did some drawings and left to her mother.
While I worked UE9, mum had asked what was I doing. And XXYL replied: "he is playing" [with his toys]. XXYL understood my fun and YL understood where I was.

Hopefully one day she will join me behind the key.
