I have a delimma - I love wine, in fact worked a bit in the wine industry. However, I have a personal conviction that I will not, under any circumstance, buy French wine. The potential issue is that next week I'll be in San Francisco, going out to dinner with a buddy who lived in Europe for five years (he's an American), who'll be bringing some wines from his personal cellar to dinner - one at least is french. Is it going against my standards if I partake of french wine he bought years ago? Does that violate my own convictions if I'm technically still not buying it? Thoughts?
