This child (girl, approx. 13-14 yrs old) is not only unappreciative of what is given to her (across the board... regardless of the gift or the giver, she says Thank You to NO ONE, and actually complains under her breath), she is also just downright surly towards others.
Her dad and stepmother say nothing to her in the presence of others attending, and I am weary of spending money on people who act as though they don't even like me.
I might add that her other four siblings (of various ages) DO appreciate their gifts and respond in kind, without being prompted to do so by their parents.
