Talking using the third person instead of the first , as if you are talking on behalf of yourself, was a very common habbit , almost a fashion just before WWII.
All the come-il -faux and sic ladies loved to talk like this.
I am used to it. My grandma used to do this when she wanted to tease us or she wanted to show that she is announcing something important.
In the European Literrature of our days, the third person is used by writters when they want to show self-sarcasm
I just mention all these because I am positive that Dear Abby is not mocking at us. It's her self sarcastic style.Wait to see her real avatar. It's great!!
I personally love this style Dear Abby and I dare to say in public what the majority has confessed in PMs.
I wish I have thought first to create this persona
As long as we have polite and intresting posts in a language we all understand.... why not
