But this week the temperature in Bay Area were relatively high, so it was surely not my allergy to cold air.  Was it possible anything related to COVID, I wondered?  My daughter told me it was most likely that I inflicted a hay fever, the allergy to pollen, which is commonly seen in California in springtime.  She also told me not to worry about it and gave me some pills to take after meal or before bedtime. 

I took one after supper, and now I felt a little drowsy.  See you guys tomorrow.
