Went out for a Christmas meal last night with 6 friends. One friend is a non drinker. We had 6 bottles of wine between 5 and half bottles between 5 of us. This morning had a phone call from non drinking friend to say we all drank too much and 2 bottles between us should have been enough. We were not merry but nowhere near drunk, not noisy or disruptive. AIBU to think that this telling off is out of order.
