Once again, incredible story telling. Two stories in one weaved together beautifully.
I’m a scent person too. I put scent on before bed, for me! I love the smell of lit matches. I bury my face into my dog for “Zaccy foost” which is a warm and delicious smell.
And as for your friend. It’s such a fine line to tread between interfering and showing love. I am going through something similar with someone close to me. I watch as they fade away in front of me. The scent lingers, but it fades. And the nostalgia is always there. Like the scent on a scarf, reminding me of happier times when their smile was genuine and wide.
