Later they're having a BBQ with friends and Mark berates her for not providing drinks for the guests. That evening they are having sex again, and Tara again is crying and in distress. Afterwards she repeatedly whispers that she is not happy, and after some brief discussion with Mark she says she's going to sleep. There is a passage of time.  answer the following question:  Who is in tears during sex?
