A conversation chez-Lu

Mama-Lu: Fasting doesn't start until your 18 right?
Papa-Lu: Um, I think it's 12 when it starts.
M: No, I think that's abstinence.
P: WHAT?!!?....wha- oh, that abstinence.

For the record:

Ash Wednesday & Lent Rules
For Catholics:

All persons over 14 years of age are gravely bound to abstain from eating meat on Ash Wednesday and on all the Fridays of Lent.

All persons over age 18 and up to the age of 60 are gravely obliged to fast by limiting themselves to a single full meal on Ash Wednesday and on Good Friday, while the other two meals may be light.
