Status Updates From Finch House

im a bit confused? so micah has lived with her mum and grandad for her whole 11 years of life, and with how things are worded, her nana is well married to her grandad, so its a bit weird that she makes a comment how when they had visits they watched her vhs tapes? did she not live with her husband or was put in a home later in life? i know its a bit of a weird thing to be hung up on but its just weird haha
