Nice, normal ILIs are scarce. Maybe non-existent, actually, and I have a lot of ILI friends. But fortunately, SEEs aren't looking for nice or normal. They are looking for crazies whom they can be crazy with, and deep inside, ILIs are more than a bit crazy. If they have good logic and are able to warn SEEs about future disasters which will happen if they keep on doing what they've been doing, that's a bonus.
