I simply do not have the energy to believe that this walking ball of abject, mind-fizzing chaos has managed to pick up another 'household member'. How, amid the spite, the viciousness, the vindictiveness, the neediness, the joylessness, the self-pity, the abject disregard for absolutely anything else in the entire universe except what her synapses are currently exploding towards, has she found the wherewithal to attract another human being of a functioning mental standard?
Unless it's Fritzl-style, of course. I could believe that. Despite the Many Ailments, I bet she's quite strong.
