Dear Prudence,
I live in Seattle, a city where so many young professionals are so bad at navigating public spaces politely that a local paper recently published a guide on how to ride the bus. I’m also soft-spoken and felt invisible until after college, and I suffer from some anxiety around asking strangers to do something. Recently I’ve noticed a trend of people invading my personal space without acknowledging me. This week I was sitting in a beer garden when one woman recognized another behind me, and then they had a five-minute networking session, each standing less than a foot from my face. I loudly cleared my throat during this whole interaction, but the two made no indication they had noticed me there. In fact, their loud conversation made it impossible for me to continue my chat with my friend who was sitting opposite me. What is the correct response in public when strangers are invading your personal space without acknowledging you first? What is the polite but firm way to ask people to please not encroach on my own good time?
