 
 Hey Imogen! I've dealt with a chatty neighbor like that before, and the key is to combine politeness with a clear exit signal. Start by acknowledging what they've said to keep things friendly. For example, if they're talking about the weather, you could say something like, 'Yeah, it's been really humid lately, hasn't it?' That shows you're listening. Then, pivot to your need to leave by tying it to something immediate. In your case with groceries, try 'Well, I better get these inside before the ice cream melts.' It feels natural and gives a valid reason without seeming abrupt.
From my experience, having a routine helps make it second nature. I'd glance at my watch subtly and say, 'Oh, look at the time, I've got to get dinner started or the kids will be starving.' If I could start over, I'd repeat that watch glance every time because it adds a visual cue that reinforces your words. Another phrase that worked for me was 'It was great catching up, but I need to run some errands now.' Keep your tone warm and smile as you say it. Over time, my neighbor got the hint without any hard feelings, and we'd still wave hello. Just practice in the mirror a couple times to make it feel genuine.
