This is a purely hypothetical question
Imagine a situation where a Sikh family living in a Western country decides to send their nine year old son (after he attempted to cut his hair due to bullying) to attend a Sikh school in the Punjab while living with relatives who are very religious. Now one of his best friends of the same age (a non-Sikh Gora with short hair) who always wanted to see India and offered to go with him and his request was granted. Do you think the religious relatives of the Sikh boy living in the Punjab would allow the non-Sikh boy cut his hair while living with them?
