A boy who's incredible, he'll take your breath away and can make you smile at the littlest things he doesn't even know he's doing. He can talk to every girl that flirt's with him but still manages to make you feel like your the girl. He is not afraid to break the rules and have fun. Very cheerful and optimistic, despite how horrible the situation may be. He isn’t concerned with himself at all, but instead he’s concerned with other people. He always knows the perfect thing to say and the right time to say it.
Being on the same wavelength is similar to the expression "We're totally on the same page" or "Great minds think alike" It means that you and the other person are similar in thinking at that very precise moment. Often this happens when you voice a thought and someone else says the exact same thing or something similar. It just means you had the same opinion on something about a certain topic, issue or whatever.
