2 was also a hard year for us!
When my DS was a late 2 he stated very loudly in a restaurant "that lady is fat" I wispered sweetly in his ear about volume, choosing nicer words, and so-on, which made him mad so he then replied back in his rude loud voice "Fine! she's not fat she is over weight"
The worst part about it was that the lady was not fat, size 12-14 maybe?
We are now on the up side of 3, and I can report that his temper, volume, and couth have improved.
The only thing I can recommend is patience and practice. We had to have alot of "little talks" about what was appropriate or not and why. Gradually my DS started to catch on, but he is still a work in progress.
Role playing about what would have been a better choice may also help as your DD gets a lil' older.
And lastly don't stress too much, your DD is giving you some fun stories to laugh about later!
