The bag kept ready can mean enthusiasm for leaving or uncertainty about staying.

The same habit can come from two very different places. Keeping something permanently packed might be the mark of a person who loves going, who has made departure easy because they intend to do it often. It might equally be the mark of someone who has never quite committed to being here, keeping an exit within reach. From outside the two look identical, and sometimes they do from inside as well.

If you keep something ready, ask which it is for you at the moment. Neither answer is wrong, but knowing tends to change what you do about the staying.
