When I lived in California I shared a house with my friend Vernon. I was in one room making up some wood arrow, P.O.C. and I cut the to length. I took one of the nubbins into the other room and toosed it to Vernon and said, "Take a whiff of that." he did and then asked,"Do you have another one of these?" "Yes" and I went and got it and tossed it to him then went back to making my arrows. While they were hanging up and the ssealer was drying I walked back into the living room where Vernon was. There he sat with one bub in each nostril. I guess I had a bewildered expression on my face because he simply said, "Aroma Therapy."
