I feel really uncomfortable with how kids are not always told to call adults Mr. or Mrs. anymore. For example, the mothers in my building (we are not friends, just casual acquaintances) all refer to me by my first name to their kids, not Mrs. Soandso - for example - "Billy, hold the door for 'Jenny'!" I am at least 10 years younger than all of the mothers (I'm in my early 30s) so I feel foolish asking them to say Mrs., but I don't like 10-year-olds calling me by my first name.
Basically I have only once ever had a parent (my boss's wife) have his or her child call me Mrs/Ms/Miss whatever. Sometimes I get "Miss 'Jenny' ", which is better than nothing...
If I am able to I have children I think I intend to tell them to address adults by their last names - but is this hopelessly old-fashioned? I still call my friends' parents Mr. and Mrs...but I have noticed some of my friends not doing this. Obviously close family friends go by first names.
What are people's thoughts?
