In her favour, Stephanie is full of enthusiasm and generally 'happy' in her disposition
The thing that gets to me most is the way she deflects away from her own shortcomings by laying blame somewhere else
For instance, when she canoodles with Jeremy it's not the canoodling that's wrong ... it's people mentioning it
When she dumped Megan's new clothes in a sodden heap on the floor, it wasn't disrespecting someone else's property that was wrong ... it was Jeremy throwing her in the pool
When her dirty knickers get 'shown' it wasn't leaving them lying around that was wrong ... it was the 'showing' of them ( she does have a point that it was unkind to expose her underwear, but she completely disassociated the unkind act from her own slovenly behaviour ... like the one had nothing to with the other )
She seems unwilling, or unable, to make the connection between her own behaviour and the consequences that follow
That's my main beef with her, although, that said, she's been a real value for money housemate and I'm glad she survived the last eviction
