Good mothers usually can be counted on to support their kids even when their performances/actions are less than perfect or adult-professional.
To wit, the Infiniti ad in which the mother seals herself off in her Infiniti from her child playing symphony music with other kids–less than perfectly. Then she is all praise and smiling when the kid has finished making imperfect music and back in the car.
Revealing a selfish, self-centered, phony, hypocritical, unsympathetic, unsupportive mother more snobbily concerned about her own self and pleasures than about being a good mother. In short, a ‘proper’, potential Infiniti woman-owner.
