Strange visitor

My mother in law is in town, staying at our place. For a month. My son, who hadn’t seen her in several months, was scared of her. He hasn’t completely warmed to her yet, though he at least allows her to pick him up, feed him, etc. I suppose when he last saw her his long term memory hadn’t developed to the point it has now. My Japanese hasn’t developed to the point where I can have a meaningful conversation with her. I can communicate, but only on a childlike level, lol, like I can’t tell her how I’d like to throw everyone I work with (day job) off the top of a tall building. However, I suppose that’s info she can do without . . . .
