Do smiley faces during text indicate he may like you?

He uses then a lot and :P faces too. He's 28 so I'm guessing he doesn't use them unless he's actually smiling, it's really cute when he does it, does it mean anything web a guy sends faces after texts. Like good night :), or ha ha thanks :P type texts. We don't see ragout her a lot even tho we work in the same building. I sent him jokingly "hey maybe we can talk in person sometime" and he responded ":) we will". We see each other quickly in passing, so I sent him that after I saw him, it's a good sign right?
