Have you ever been put off by biased word choices that another person made while communicating with you (in writing or in person)?

Have you ever been put off by biased word choices that another person made while communicating with you (in writing or in person)? In the matter of age, for example, has an older person ever referred to you as a “kid,” even though you think of yourself as an adult? Conversely, if you’re an older student, have younger students ever referred to you as “grandma” or “grandpa,” even in a humorous way? What affect did these word choices have on your relationship with the other party?
