There is something ritualistic about coffee.
I think that is what I enjoy most about it.
There is also something soothing about drinking hot drinks.
I have a coffee in the morning most days.. but it's after work or early evening that I enjoy coffee most.. I also have an addiction to nesacfe instant cappuccino and will drink those through out the evening, It actually helps me sleep most times.
I am not a big drinker of booze.. so coffee replaces the beer for social meetings as well.
