Firstly I would like to wish Estherh and all those in need a Refuah Shleimah.
Secondly, it is as important to watch our words when we speak to each other about simple things as it is not to speak loshon horah on others. The simple choice of words can change the entire meaning of a person’s intentions. Saying that she couldn’t “be bothered” makes it sound like Purim and shelach manos is an imposition or inconvenience rather than a mitzva we should look forward to perform.
Perhaps if she chose to say “I can’t deal with shelach manos this year, I feel so overwhelmed or tired…” the intention would be clear and not misunderstood. I know a lot of people who couldn’t be “bothered” and chose to be away from home for the chag. The fact that she was home, reciprocated in the giving and receiving makes me think that she chose the wrong word to describe how she was feeling.
