Certain smells and/or odors take us back to our childhood or places. For me, the smell of a burning cigar reminds me of Dodger Stadium. Another smell is that of burning incense at Catholic mass. This smell reminds me of Christmas eve mass.
In my early adolescence, mass was boring as heck for me. Especially because I remember it being held in Latin (what were they thinking?). Mass became more interesting when the padre (priest) began to have mass in ingles and or español.
