I've just had the most irritating conversation with an extremely annoying young man, who tried to convince me that stuff you do at home, like bringing up kids and housework, is not work because you are not being paid for it. BUT - stuff you do as a favour to a friend, like going round and helping him build his outhouse or shed or whatever, is work, because although you are not being paid for it, you are not doing it for yourself. BUT - if you are a self-employed man running business (you've got it - for yourself) that is work, because it is how you make your living.
Can somebody please define work for me?
