Difference between a priest and a bishop

Today Claver Jr, 8 years, surprised me:
- Daddy, are you happy for Bishop Jason?
- Is there any reason why I should be happy for him?
- Yes he is celebrating his 4th anniversary as bishop of Barbados.
- Then I am happy for him and wish him God's blessings and all the best. By the way do you know the difference between a priest and a bishop?
- Yes I do. The bishop has a red hat, the priest has none.
- OK. Something else?
- A bishop is young and a priest is old.
- I did not know this.
- It is true, Daddy.

En fait les prêtres que Claver connaît sont tous d'un certain âge: Fr Clement, Fr Michael, Msgr Harcourt. Et l'évêque Jason est plus jeune que tous les autres.
