You can tell from six

Some movies just have great lines of dialog that stick with you. It’s not just the lines themselves but the way they are delivered. Here’s one such scene from Sliding Doors
that sticks with me.

[Helen walks into the room holding a pregnancy test]
Anna: James?
[Helen nods]
Anna: Since last night?
[Helen stares]
Anna: Sorry.
[pause]
Anna: You can’t tell from one. They can be inaccurate.
Helen: I bought three packets. Two in a packet – that’s six. You can tell from six.

And for the record, we could tell from one.
