Definition: Signalling is when you subtly hint at something to someone else, often without actually saying anything directly. Imagine this: you're out shopping with your best friend, and one of them says "Hey! I found a cool new pair of sunglasses in the store!" As they turn around, you suddenly notice that their shirt is buttoned up tight. You feel like it might be a sign that you should look for something else.

Example sentence: "I just saw an ad for those really great shoes at Target and I'm thinking about getting them - but can I still take a peek at your outfit to see if I looked cool enough?"
