I often bring more than I plan on actually opening to a bottle share and open the ones that most people haven't had or want to try. Not yours don't open it. Simple. However I unfortunately have had much of my beer drank at my house without me by douchbag roommates. Most recently a 2008 panepot (sp?) reserva that he won't fess up to drinking. I want to live by myself so bad. To clarify the worst damage was done by one person who no longer lives with me and the reserva when I asked him about it he said he drank a brown Sugga so it could have ment to drink a Sugga but grabbed the reserva.
