laugh out of the other side of your face/mouth, you'll/to

You’ll be sorry; to feel anger or annoyance or disappointment after having felt happy. This term dates from the seventeenth century and was then spelled out by Giovanni Torriano (1666): “The English say, when one has conveniently reveng’d ones self on another, now you can laugh but on one side of your mouth.” Later it was sometimes put as laughing on the wrong side of one’s mouth.
