- Put yourself in their shoes
- Think of times you’ve been in a similar situation and explain your reaction
- Can the behavior be explained by a more “universal” model than a person-specific one?
- How are they empathizing with you, given they are projecting?
- How are they empathizing with you, given what you know about how they perceive others?
- What successful model have you used to explain similar behavior for similar people?
- Is your conclusion affected by your attitude towards the subject?
Emphasis mine. My dictionary contains four instances of "lie" as a noun; #3 applies, and #1 (the one you're using) applies under the interpretation espoused by the person whose comment I was responding to (i.e. TimS suggested she wants him to conclude, for now at least, that nothing is wrong).
If you have read TimS correctly, then we agree that she was lying. But your reading of TimS doesn't look very plausible to me. Alice's not wanting to talk now doesn't convey the message that nothing is wrong now.
