I suppose it *is* possible that LW's sister did choose to send what she considers a "boy" gift to a child she secretly still thinks of as a boy.

However, if she did that it's more likely due to misguided and transphobic "good intentions" than as a desire to piss of LW.

At any rate, if Isabella is happy with the gift then there's no use worrying about it. If Ashley really is a transphobe she can't hide it very well for very long.
