Yes, and the speed of it is bonkers. I can understand something like that being the start of the conversations - 'I've been thinking, living on this busy road is stressful with the children, I'd really like to start looking for somewhere in the country...' and the next 6 months or a year being taken up with weekend drives to scope out potential places to relocate, job prospects in the area, schools etc. But nope, not for these two. within three weeks Tim had resigned from work, their house quickly sold, and they moved to a rented house near Criccieth to begin their new life.
Either they have a long and troubling history of making impulsive, ill-thought out and irresponsible major life decisions, or there's more to it than that. (I know which I'd put money on.)
