tell-tale toothbrush

this morning i spied a toothbrush
on the floor.
i won't tell who it belongs to.

did i -

a.  scream, "grody!" and throw it out?
b.  start a pot of boiling water to sanitize toothbrush?
c.  hold toothbrush under hot running tap water for 30 seconds?
d.  rinse toothbrush off quickly and throw it in the drawer?
e.  pick up toothbrush and place it on the sink?
f.   walk right by leaving toothbrush alone?

i'll never tell.
thump, thump. 
thump, thump.
