Interesting reading Peter's Pottery blogpost
When The Carpenter goes out, even if he himself doesn't know when he'll be back, Teigar does. AND she'll be at the right door, waiting, not necessarily the one he went out.
If she's having a day on the cushion on the windowsill, within five minutes before he arrives, she'll turn to face the window instead of warming her back in the sun.
When The Oily One returns from work, which is not a regular time, she is there to greet him and to tell him off for not being here!
