he can do whatever he wants.

was in the same situation before with my stepsis. hated her for that.
its a free wprld can do whatever we want, now if we get in trouble we should not blame anyone else.

i think your friend will not be in this situation if he knows the limitations. sometimes we got so drunk and never notice the time because we enjoying the party. maybe that is what happened to your friend thexonic.
