Waffle dad is awful, but I can't believe you all hate him more than Topsy and Tim's dad.
From my years of carefully study, I am as sure as I can be that Mr TT is bonking a succession of colleagues at work, while gormlessly refusing to do any housework at home. He tries to instigate "fun" rough and tumble games at National Trust properties, where he jumps about, feints a bit at his kids, throws a leaf in the air and shouts "Yeah!" and "Good job!" at nobody in particular. He will expect you to invite his mother to live with you, when she decides to downsize at the "frail" age of 65. She will sit on her money, like Smaug on his horde, until she is 82,pops her clogs, and leaves it to the cat's home. The Twins, at this point, will be at/have finished their studies at Goldsmiths,if they haven't flunked out. Topsy will be snorting coke at art gallery parties, and Tim will be working in a factory as he is funding his second trip to Thailand, this time he's going to get a job as a bouncer at a strip club and stay there for the foreseeable.
Meanwhile Daddy will have found a younger colleague who is daft enough to marry him, will claim Mummy was always a boring old nag, and will pop off to start family no 2 with the totty.
He will soon regret this, as Mummy retrains as a therapist and moves into a minimalist flat with the dad of Tim's little friend. Is the friend called Peter? The dad is fit and does DIY
