My girlfriend and I bought a bottle of vodka. We drink like 75% and she tells me her friend wants her to save the rest bottle for them to get drunk. Am I wrong if I told her no? We got the bottle to drink together and I asked her if she wanted to drink again because its at my house and she was coming over the next day. Then she tells me no her friend wants her to save it for them to get drunk. I told her no and now she's mad at me.
It's not your job to supply people with alcohol. A wise man once told me if you want something get off your ass and go out and earn it. You have every right to say no, unless you're invited to drink it as well.
