Is she just pretending to be nice?

Yesterday i came home to find out My Mom has covid.

Told by Boss by text she called me she sounded rude to me.

so she came in this morning before she had to go helpout another store. Told her she was rude she got upset i don't care.

She called me a few seconds ago asked me how i was doing i said not good she asked me if she could do anything for me I said no she said if that changes let her know

Is my boss just pretending to be nice?
