Penny Blossom

[Tuesday Pajamas]

Penny doesn't like being alone. She takes up with guys because she's unhappy when she doesn't have anyone in her life. This suggests to me she is afraid of self reflection and possibly even a little depressed. Leonard was there and to be with him seemed like the better option, in her mind, than being alone. But deep down she knows there's something wrong so she can't quite bring herself to commit.
