Shadows Are Not Always Darkness
Peter doesn't ask for trouble, trouble just kind of finds him, stalks him like a bloodhound until it's basically his second shadow. Tony doesn't ask for stress, stress just sort of follows him around, pads after him like a puppy turned spider-baby, until he's basically Tony's second shadow.
Tony, somehow, learns to love and cherish his little stress inducing kid. Peter, on the other hand, just wants trouble to stop biting at his ankles.
