what is normal isn't normal

i have being reading about a text called What is normal isn't normal What is normal is weird for other people and what is weird for us is normal for them weird is normal if someone says you're weird it turns out you're not. everybody has their own interests adn that means that everyone is different. So what's normal for one person is not noraml for anther one. So that means that what is normal for one is not for othe one we don't really know what people do outside of school/work. what is normal changes in time,different locations and cultures.
