See, that's the whole thing behind abstaining from meat.
My mother is fanatical about not eating meat on Fridays during lent. But then again, she doesn't eat much meat anyway because she has problems with digestion. Where's the good deed in that?
I just think that sometimes Catholics (and other religions, quite frankly) get caught up in the letter of the law without respecting the spirit of the law. The law of meat abstention came about when eating meat was an extravagance. Humility and respect for the teachings of God should keep in mind that the letter of the law sometimes neglects the spirit of the law.
If it's meat that is extravagant, then abstain. I say that a more likely extravagence would include sweets, soft drinks, and doing everything that is excessive. That, I believe is what God expects from us.
