だったら (hypothetical if)

In that case, I want you to grant me a wish. That'll make us even.

If it were me, I'd just watch how things unfold, though.

If it were me, I couldn't say something that brazen.

If it were me, I wouldn't do that.

If it happens to be raining tomorrow, I'll postpone departure until the next clear day.

I wish every day were Saturday.
