This is an awesome object lesson on the harm of holding on to negative thoughts.  Philippians 4:8 says what to spend time focusing on.  1 Peter 5:7 says to cast our cares on Jesus because He cares for us.  Place the “Can’t do anything about that” into the hands of the One who can and take from His hand the memories and reminders that leave you with a grateful heart.
