I love this question as it takes me back to the happiest years of every human being: childhood.
At home we all drank coffee and our first cup was almost a latte. At that time it was used to accompany any dessert or for breakfast. Because of its stimulating properties we were not allowed (my brothers and me) to drink it without milk but since I was 5 years old I have been drinking coffee, it is possible that it was before that time because I was curious to try it; I just don't remember it, but since I was 5 years old, that is the age we consider to have the use of reason. From then on the habit has been maintained.
I enjoy all desserts with a coffee with milk but little by little I have been decreasing the sugar in my coffee and I have increased the caffeine load. It is a joy to enjoy a divine black coffee and even more so if it is with a pleasant company.
