when i got drunk...

hi. me and 7 friends of mine got drunk together in a park, at 4 AM. a friend of mine (female) got really wasted and started to strip herself. i didn't drank much, and i was in control, and i stopped her everytime she started to do it. everybody said to me "why ruining the fun???", and i stopped her. she started to talk about her sex life (wich were very rich), and i shut her up. finally, i toke her for her home, and even for her bed, and i left her house. should i needed to do it?
