If a quozl is listing her grievances with you it's going to take a while, them having seven fingers and all. Quozl expressions are sometimes hard to read. The newer generation, more so. so here's a handy guide to tell if listens before talking is angry at you.

2. She is talking to you. As her name suggests, she'd prefer to be listening to things. But you've gone and said or done something so stupid, She now has to talk to you.
3. She's awake. Sleeping is probably the only time She's not angry. Yes even those times.
4. If she is anywhere near runs-before-walking
