Remember, spiders are good for people. They eat mosquitos and other desease-carring insects and they almost never bite people. They are nice and friendly, they just have a bad reputation because they look spooky with their 8 legs and their 8 eyes :)
Don't kill spiders! If you find one in your house, leave it alone or gently take it outside. Remember, spiders are your friends, they catch and eat mosquitos.
