They're taking the piss.
Remember the university students locked in their flats on campuses?
The GCSE students who were unable to sit exams?
Those like my ds2 who started work, only to be sent home with no redundancy because they hadn't worked long enough?
The sports and hobbies that were cancelled (while the tories continued to party)?
They don't owe us anything for the covid years, they had those years stolen and can now give their opinion at the ballot box.
Is it any wonder that they appear more politically motivated than previous generations at their age?
