You know what's almost impossible?  Getting my dad to follow all the doctor's rules.  Always wear your mask outside, don't touch birds, don't do yard work, don't go outside on windy days.  I wondered why my dad didn't say much when the doctor said all that.  Now I know it's because he had every intention of doing whatever he wanted!  To be fair, he is being much more careful than he used to.  But still, keeping that man out of his yard for 4 months in the spring is like keeping Hunter from playing yahtzee for four months - impossible.  The one rule he does follow, cheerfully no less, is to not be around crowds.  That has more to do with his innate anti-social nature, rather than any desire to be obediant to the doctors.
