estherh, I am so happy for you that pesach cleaning is not difficult for you and can even visualize you wearing a lovely dress and pearls and pumps of course while doing this…
its a level…B”H you are there.
While you may not mean to judge your friend of 20 years – you did.
As far as mishloach manos, maybe her feelings didn’t involve $ or amount of items, maybe it was just something within her that maybe even she can’t grasp…
Go easy, and enjoy your cleaning.
