Big flies, small flies, very small flies

Well! There are big flies, small flies, very small flies and mosquitos and they fly around their forest all day drinking and eating (I dont know what).
And then along comes Michael!
The fly siren goes off and they all fly to the place where he is to jointly suck him dry.
Now, I simply don't understand how word can get around so quickly in "fly land", and why they all need my blood when they have been happy drinking and eating other things for ages!
I try to put myself in their bodies and minds.
Yes I also eat and drink my normal food everyday, until I spot a bag of "Gummi Bears", then I cannot help eating them in one session!
But at least I eat them quickly so they don't suffer.
I don't suck them dry slowly, causing great suffering like the flies with my blood!Meer informatie
