When a person tells you he wants to be with you but he wants to keep the relationship underground, you know it's BULLSHIT.
When a person tells you he likes you but he can't accept the fact that you're his best friend's elder sister, you know it's BULLSHIT.
When a person dates you and the next thing you know, he's telling you he's a bird with no legs, again, you gotta know it's BULLSHIT.
