Dear teachers,
Would you be kind enough to give me your considered opinion concerning the interpretation of the expression in bold in the following sentence?
Miss Carter…said the children had given her some flowers… It’s a delightful gesture and Miss Carter, I may say, was tickled pink about it.
be tickled pink = be delighted, be very satisfied
V.
Yes, "delighted" is a good synonym.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
