What I took from the interview is this:
* guy who hasn't had many good breaks/opportunities in life
* probably in trouble and blamed for things from early childhood on
* inferiority complex and deprived upbringing and life
* has a record like many, most likely, from his environment
* desperately wants and needs a home life, aspires to a 'respectable' life and has attempted to create this with who knows how many women. What we have been told is that he was in a relationship with Tia's mother. Then, when that fell through, he probably turned to Tia's grandmother in order to cling to semblance of family and a roof over his head
* unemployed and close to emasculated. In the interview he recounts the purchase of sweets on Thursday afternoon with Tia. Tia ate 3 and wanted also to eat the last but he stopped her, explaining embarrassedly that if the grandmother returned from work and discovered the empty packet of sweets, she'd be angry. That speaks volumes right there - the grandmother, employed and source of money in the household, wears the britches and would be annoyed if there were no sweets left for her (as if she needs them)
* attempts to play the indulgent father role with Tia, explaining in the interview he'd given the child ten Pounds 'as a bit of pocket money' and to teach her things in life should be earned (pocket money in return for assistance around the house) although it's highly probable the money came out of a housekeeping allowance provided by the employed grandmother
* was focused on what he'd done that day because, imho, he is answerable to the employed grandmother and because he earns his keep, basically, by functioning as a house-husband. It's to be suspected, imo, that if the household tasks were not done, he'd be in trouble when the grandmother returned home, including by the sound of it, remonstrations about Tia's soiled clothing being in the laundry basket. To me, it sounds as if he lives on his nerves and washed Tia's clothes in order there be no reason for the grandmother to bawl him out
