After a period of time, she would always return a gift of comparable value.
If the gift he gave exceeded what she could afford to reciprocate, then that gift would ultimately end up sitting in the drawer of her bedroom.

She never used the identical laptop he had bought for her.
She claimed that she felt more comfortable using her old belongings.
