In some cultures, the Dad would just have taken the cell phone. However, diversity is our strength, and these differences are why we have to import people from a variety of cultures.

The boy was probably shocked that there other options besides sheep and goats.
Anyone who thinks this is okay by any stretch of the imagination needs their head examined. I hope that “father” rots in prison.
