Tyson’s father purposefully forced Tyson into having an isolated childhood, an attempt to make for his ‘failings’ with Jethro and further groom Tyson into being - what he saw as - the ideal heir to the Delaney family; which became something of an obsession after Anne left.
As such, Tyson didn’t have many friends. It took him a long time to properly build up his social skills and he was incredibly isolated from those he tried to make friends with. His life was completely different from those at his school and he was an easy target for bullying; especially as the rich kid that no one needed to feel bad about pushing around.
Leaving secondary school at fifteen to attend Cambridge University officially certainly didn’t help Tyson find a place amongst his peers. The two most notable ‘friends’ of Tyson’s childhood were Peter Campbell & Alistair Mandelson, who only appeared once Tyson was a teenager and were paid to be his friend by his father.
