Is it good or bad for the mouse to get into the trouser leg and climb up?

My family always thinks that meeting mice is not a good sign. From my mother's childhood to my childhood, every time I met a mouse, something bad happened, big or small. It's not that mice are bad. Every time mice don't destroy things at home, something bad will happen as soon as they appear in front of us. Like a crow, this is a bad sign.
