Sometimes our good deeds do come back to "haunt" us

Yesterday I finally managed to line up an audition accompanist - hurray!  Better, she's someone I already know, as she directed a show I was in 4 or 5 years ago.  I also gave her daughter rides to several "Yeomen" rehearsals and performances last year.  Because of that good deed, D quoted me a rate for 4 hours of her time that is only slightly more than I pay for a 1-hour voice lesson - a very friendly rate indeed!  I told her that her daughter had already given me a thank you gift for the rides, but "this is from a very grateful mother."  Happy to oblige!
