I just want to let you know I was not trying to belittle your discomfort and unfamiliarity with Macs and Excel. I do understand that you were, instead, just not expecting that job to have to deal so much with computer spreadsheets in general, let alone a different operating system and a specific program.
Like I said, I know you'll have the next position lined up in no time. Your kindness and sweetness alone will again land you the next one.
BTW, do you use a lot of emoticons on your resume too? (Just kiddin' ya'. )
