Usurper

The second Missy Ann got up from her chair to cut a piece of fabric for her latest quilt Liffey jumped up in the chair to keep Missy Ann from sitting down before giving the attention the little dog knew she deserved.
Liffey has a definite schedule in her head and she lets her humans know if they deviate from it (unless it's for a snack or a walk or a wrestle or anything else that's for her benefit).
