You know if you've upset someone on the reincarnation committee if you come back as a spider (or for that matter, a frog).
Your chances of survival to adulthood, and mating (which is what adulthood is all about, isn't it?) are slim, as although most
people don't habitually eat invertebrates (we make an apparently arbitrary exception for arthropods that live in the sea),
most animals that eat other animals will have a go at a spider. So spiders rely on having a lot of babies, being secretive,
and usually coming out at night, unless they are very fast or live in a web that is strong enough to upset a bird. While the
reaction to a picture like this amongst many people is "ewww!" or "Yuck!' (or even "Aaaaaaugh!!" and then hitting the
computer with a brick in more extreme cases), the reaction of many bird species would be "Yum!" (or the Avian equivalent).
Spiders are eaten by birds, lizards, frogs, centipedes, other spiders, wasps, praying mantises, fire, flood, and other acts of
god/s/fate/unfolding of a developing universe (delete where not applicable). Just in case there IS a reincarnation committee,
let peace be your motive and compassion your guide. Or practice hiding very well.
