Conversation

I visited that old park yesterday, and it looks so unimproved since the last time I was there.

Really? That’s a shame, I thought they were planning to renovate it.

Yeah, it feels like they’ve just left it as it is, unimproved and all.

It’s disappointing when places like that don’t get the attention they need.
