We raised her to be independent, and not to be like some young adults, who stay at home with their parents well into adulthood, never really take any responsibility for anything, never save any money, leech off their parents, and litter up the neighbourhood with all their cars.
So far so good. Till the pandemic struck and DD found herself back in her teenage bedroom studying online. (Lots of DHs younger colleagues fled London and returned to parents. More space, more garden, so easier to wfh.)
And if DD ends up working in London we would prefer she came home and saved for a deposit than spending a fortune renting a shoebox.
The irony is that Sadiqs decision not to issue any more resident congestion charge discount permits is that DD was incentivised to bring her car back and park it on the street, rather than store it off road through the pandemic. If she does return to London she will be one of an increasingly small number of residents with a car. (Even two decades ago only 30% of residents had cars, and new housing is built without parking spaces, and new residents cannot get resident discounts.)
Having said all that, we and DD rarely use our cars. Public transport and an increasing array of hire bikes means that day to day there is little need.
