That's a shame
A light, kind reaction when plans fall through or news isn't great.
Examples
Oh, that's a shame. Maybe next time?
That's a shame they closed the old bakery. I loved it.
In a conversation
A: Sorry, I can't make it to your birthday dinner after all.
B: Oh, that's a shame! We'll save you some cake.
Common mistake
Not: So pity!
Say: That's a shame!
"Pity" is a noun, so "so pity" doesn't work. Say "That's a shame" or "What a pity".
