I know I'm probably overthinking and I watch a lot of crime shows but I am constantly worried some stranger will overhear a conversation between my partner and me and rob us because they find out some personal information like how much our salaries are or just like when we're out and about so they know when to rob us. She talks very loud and we're in the center of a big city with a lot of people so that's why I'm concerned.

Is this a rational thought?
