We Pause for a Brief Station Snark
If you give your child one name but call her/him something else (e.g. her given name is Hortense Edwina, but you call her Eddie) PLEASE teach the child his/her full name. Otherwise, Eddie may have meltdowns of epic proportion upon entering school and being called, over and over again, "Hortense".
"But that's NOT MY NAME!" I hear again and again, in tones of such outrage that you would think I had called the child something obscene. Drives me batty.
End of rant.
