The fact that one brother has birthday cake sliced while younger brother is smiling doesn't imply that a pair of brothers celebrate their birthday together.


Context: "Sitting at a table with beer empty beer mugs on it one brother is has a birthday cake sliced with sprinkler lit up while the younger brother is smiling with his eyes closed." Claim: "A pair of brothers celebrate their birthdays together."
