Hi Clara Lou,

***What problem do you see with the construction?***

LOL! I'm not gonna go look that one up as I did a while back when a bunch of us had the same conversation about putting "I" ahead of another noun or pronoun. But it's still, according to my source, correct to list others ahead of yourself. As someone said, it's kinda like offering another person with you a piece of candy from the candy box before taking any yourself. So your construction is correct, but it's a matter of courtesy.

Agreed. That's what I was taught in grade school. But I think it's nitpicking for the original poster to claim the writer made an "obvious mistake in grammar."
