36. He (Eagerly) Helps You Out
Let's say this is a guy you work with. At work, just look at how he treats other people compared to you, and you'll immediately be able to tell if he likes you.
If he helps you out with whatever you need, he's on your side during meetings, he tries to make you like him, then you know he likes you. Maybe not in a "I want a relationship" kind of way, maybe he's just attracted to you, or thinks you're cute. The best way to know is to test him. If there's some big task and you need help with it and ask him if he'd help - how does he react? Is he eager to make time for you or does he easily dismisses you because he has "too much stuff on his plate right now?" Keep testing.
