The Ex-Boyfriend: Hopeless romantic Tom (Joseph Gordon Levitt) hooks up with the world's most perfect girl next door, Summer (Zoe Deschanel), while they're working at a greetings card company.
His Post-Break-up Behaviour:Tom is dumped by Summer when their relationship begins to crumble. This sends him into a deep depression. From sporadically shouting aloud his disgust in songs that remind him of her to filling greetings cards with cynical messages, Tom acts out all of our worst ex-boy/girlfriend traits. Damn you, Tom.
