Very hypothetical, for sure. Might just as well flip a coin to make the decision. Important variables would be her sense of self-sufficiency, ability to take care of herself and maintain control of the social situation. Some kind of cautious interaction first, like leaving a note, etc. might be better than just stepping out into the open.

More likely she would first encounter a group, hopefully of mixed sex, which would have better odds than a group of guys.

Mostly when the situation comes around, if it ever does, we will just all have to deal with it, considering all the host of variables that will be in play.
