Why is she okay with touching the towel THA KOMI BOUGHT?
The towel is wrapped in plastic, so the inside is presumably clean.
Besides, OCD has never been about logic. It's all about the person's level of tolerance.
After all, technically, everything's dirty. Bacteria are everywhere, even inside our food and bodies (any idea how many bacteria live in our digestive tract?). Dust is everywhere, at least everywhere where there are living beings (dust is among others a product of particles of hair and skin we shed every day).
In other words, if people with OCD were truly logical, they'd most likely suicide by drinking disinfectant. In reality they don't (or most don't, in any case). Either they're not aware of the omnipresence of "dirt", or they've learned to cope with the fact that they couldn't possibly survive without that small ecosystem they've got running inside their mouth and intestines.
So while this clean freak's OCD "makes no sense", it doesn't make any less sense than OCD in real life.
