Did you bring your soap? ,M: No, I don't have soap. ,F: Well, you can buy some over there. ,M: Thanks. OK, I have my soap. ,F: My god, you really bought a lot. Why do you need so much? ,M: I don't know. I want my clothes to be clean. ,F: But you can't use so much. The machines won't be able to remove the soap completely. On the contrary, too many bubbles trapped dirt, allowing bacteria to build up.
