My dad looked at me funny

well dropped his keys after handing me my purse and my hand touching the bottom of it and me cleaning my hands with sanitizer and the part of my purse I touched, too.  We were bringing in the groceries.  He cleaned his hands extra clean at home.  It's funny at the gym I cleaned something just in case someone went on it, too, and people seemed to notice my worry.  It's just how it was.
