I love providing a safe space for my Little to relax and let go. To be able to do things for her. Repairing clothes, dressing her, brushing her hair, cleaning her house (we don't live together), being a shoulder for her to cry on and being strong enough to easily pick her up in my arms and carry her around.
But mostly I love being called Daddy. I tingle every time I hear it. The words "I love you Daddy" from her lips is quite euphoric. It makes everything I do for her a pleasure.
