Don't you think it's a bit of a cheek that someone has asked me to temp for them, but never hear from them

Question

from one month to another? I have sent this girl many, many of those FW: jokey emails and never receive them from her, even though she gets them. I also sent her a lovely Xmas e-card, but never got a thank you or any Xmas wishes, even though I've worked my butt off when she was on leave for her (we're secretaries and I temp and she's permanent). The only time I hear from her is when she wants me to cover her leave for either 1 or 2 weeks in the year. She says she does love receiving my FW: by the way, but I can't understand why no appreciation on her part.

Answer 1

what does "a cheek" mean?

What is a FW?

Thanks,

P.S.

Answer 2

Don't send her anything.  Then your problem is solved.
