Picture this: I’m making the arduous journey back from Trader Joes to my apartment with a heavy tote of groceries when my mom calls out of the blue. You always have to answer the phone when mom calls, right? But with my right hand holding my bag firmly and my iPhone stowed in my purse, I’m torn between letting the call buzz out (possibly sending my mom into a panic) or attempting to awkwardly tap the answer button with my nose.
