"Hey, I was wondering if you wanted to hang out sometime?" (A tad nervous, with a curious tone)
"Hey, let's hang out this weekend!" (Giddy, with a happy tone)
Do you think the first quote expresses someones feelings toward someone you like? Do you think the second one sounds like something a friend would say? Try putting yourself in that situation, and tell me what you think. Personally, I would say the first one if I had feelings for said person, whereas if it was some cool girl to chill with it would be the latter.
