Sounds like you work with some immature people. It was kind of you to realize that the elderly gentleman was probably not able to talk any more clearly, dear. You know, you probablbly don't want to be the kind of person your work mates would like´, since they wold probably only like people who were shallow and immature like themselves. Try to see them talking about you as a sort of recommendation; you certainly don't fit in with the type of people who make fun of old folks! HUGGGGSSSSS dear.
