If you see dirty pictures on someone else’s phone, that’s your problem. And a reminder: Dear Prudence is not a tax attorney, and neither is her guest, Toast co-founder Nicole Cliffe. Your questions today revolve around missing the mark. I’m always the one chasing down my sometime lover — am I being a stalker? My friend’s husband asked me to donate towards a surprise luxury car I know she doesn’t want — should I intervene? I had a fight with a longtime friend —and I don’t miss him. Do I have to try and mend things? Plus: Ditching one party for another hosted by someone you like better. Hear more Prudence by joining Slate Plus: Slate.com/Prudiepod.
