I am quite scared about posting in this topic so be nice to me please.
I am sending a note-card to the headmistress of the school where both my sons attend and I am a student also.
It is an informal note expressing thanks for support she has personally given me, it does not involve the children at all.
My dilemma is she may not know who I am.
I would like to write who (whom?) the card is from on the envelope.
How would I go about this?
