He says that cute girl at work is just a friend, but the knots in the old oak tree tell a different story.

3. A prick of the needle bears no blood.

Has he been acting strange recently? Maybe he seems exhausted all the time. Maybe he hasn’t been answering his phone. Maybe you pricked him with a needle and he didn’t bleed. If that last thing is true, he’s found someone else.
