If they’re anything like my mother, they automatically assume anyone speaking in any language other than English within earshot of her is shit-talking her, specifically. The thought that someone might be saying something mean-spirited about her is just too much for her tiny brain to handle. If you think she’s a bitch, she needs to know. It reeks of desperation and the need to be liked by all people at all times while also doing nothing to bridge that gap yourself.
