Slightly different scenario, but when the boats of refugees from Syria were landing on Greek islands, it was reported that the women often asked for eyeliner (and it was true, I saw for myself) it might see ridiculous or silly, whatever, but it’s a small, inexpensive, personal item which can be put in a pocket. You feel you look nice with it on. Like you used to wear.
I think the lipstick is similar, but it’s not about the lipstick (or eyeliner) you could give many little items like a pen or travel toothpaste set, a little key ring, which would give the same joy. People who have nothing and whose near future doesn’t have any guaranteed home, comfort or joy would be thrilled. Especially a “woman’s“ product which nobody is going to steal from you, unlike food or money.
The “ick” factor is Sali using the story to extol the virues of make-up, its “superpower” as a beacon of light in a dire situation. It wasn’t special because it was lipstick, it was getting a little special gift. It could have been a tube of sweets. A tub of Vaseline. A ribbon.
Then to bring in her Jewish-adjacent status, to justify that her extended family didn’t find it offensive is just (what is the word? I can’t think Im too annoyed.Low? Disingenuous? Trashy? Classless? Manipulative? )
