honestly what did you think he would say? 'Yeah, I was hammered' was not about to be his answer whether he was sober or not. His decision to attempt the walk is consistent with being drunk, we all know that person who will always claim they'll just 'walk home' no matter how far away it is or what the weather is. The behavior is also consistent with a young dumb kid who still has a developing brain. His being sober or drunk cannot be confirmed nor denied. BAC half full or half empty?
