Apologies for typos and rubbish formatting I'm on my phone.
I present my case:
My inlaws including my sil and her family all moved away from their childhood town. They have made their lives together in this new area. We visit as often work/school /our family life allows. We know the route from the motorway to their house, how to get to the tesco express shop for supplies, the park and the church hall where they once held a birthday party. But We don't have an encyclopaedic knowledge of their town and surrounding area.
An example of a conversation I can have with them. We arrive at their house to visit them. Sil and her children are not in. I was expecting her to be here. My children were looking forward to seeing their cousins. I ask Mil where she is. She's at Merryfield * (fictional ambiguous name for anonymity). Oh, I say. My brain desperately searching for a clue. I wonder if it's a person, and I've miss heard her- Mary field? Could it be the recreation grounds, a garden centre,. Nope I'm still not sure. So I ask again. What's that. It turns out it a soft play centre. Ah, I see. I think to myself I wonder when she will get back. Is it far I ask? Mil answers, it's on bridge street. I've no idea where bridge street is,I reply. Mil says it's near the big pet shop. Me, silently seething. I don't know where that is, how far away is it? Mil, it's only 15 minutes, but she's gone with Freddie and Emily's mum. Me silently, who the fuck are Freddie and Emily and why should that affect the distance to softplay? Adding people who you have no idea about in to the conversation just makes it even harder to navigate. I tilt my head and look puzzled. It turns out that they have a regular softplay date and Emily has a dance lesson afterwards so that dictates what time they leave. Omg, it's painful.
I always make a note of qualifying places with a general noun when talking to people who aren't local. So for example our garden centre is called Whitehall. That could be anything. So I would either say just we are going to the garden centre, or we are going to Whitehall - the garden centre.
