Calling others by the name of one's parent

Hi,

Normally, one may not call his parent by name; this is a measure of respect. [See the previous post for more on this.]

What about one who is with a group of people which includes his parent as well as someone else who shares his parent's name? This is fine if the name is generic, so that all who are present will realize he likely isn't referring to his parent, or if it is clear from the context that he is not referring to this parent.

(Rav Moshe Feinstein, Igrot Moshe Yoreh Deah 1:133)

Have a great day,
