Respect the goose

"You better be careful," grandpa said as I stood in front of the gate. It was a huge slide door over 2 meters high. Behind it was an old orchard which was guarded by geese. His geese and if you could enter at all it wasn't said you came out alive. At least that was what everyone believed.

Grandpa was the one who could enter without being chased or attacked and while he did I waited for his return.
His geese must have a super hearing. I rarely saw them approaching or pass by the gate except for those moments gradpa showed up.
It was a mystery what he did in there. Perhaps he brought them some food or water although I never saw him take something along. Perhaps the orchard was his secret place one he didn't like to share with someone else? I never asked if I could join him inside.

Grandpa... I didn't know if he liked me or took me for granted. He never hugged me and seemed to be closer to his animals than any human.
I watched the gate from a distance and observed how he came back accompanied by one of his geese. It was a big one and white and I wondered if it was true what my grandpa said. Did the geese say he was mad or was it their way of greeting, talking to him?

"Just respect the goose," grandpa said on the way back, "respect the animals and you will be fine."
