My mum's chief excuse is "well your grandma was a REAL bitch, and I'm just cranky SOMETIMES, so you should damn well appreciate me"... And my exes? One of two - either really verbally abusive domineering and mood-swingy (and generally constantly leaving me for blokes who, like their own daddies or something, would beat em up and thereby actually make them *happy*), or normal but I'd get bored for no apparent reason and end up leaving (one bitterly flat-out told me: "you need a bitch who doesn't value you, else it just doesn't feel right, does it?").
