It's enough, and it makes some sense. There's likely no clear pattern as things can be unpredictable here, but as unfortunate as it is that you experienced it at all, it does help give some guidelines for potential cases in the future.

Hopefully it doesn't occur again, but if it does that you are better able to seek assistance from those you know.

[Despite what Ferran anon said earlier. Yeah okay, fine, maybe he won't actively try to have a better attitude, but surely if he had some warning he'd at least want to try and stop it??]
