"My son is in IT" (FWIW, we're of Indian origin, living in the DC metro area for 30 years) But I don't know what to tell my parents, saying "he builds software for a living" isn't really that much more specific, and they resort to "My son is in IT" I got slightly more curiosity with "I build Apps" when I used to build mobile apps. But not with my parents.
