A group of guys
promised to buy a birthday cake for a friend
who will be celebrating in few days.
But one guy convinced the others
that he would just bake the cake himself
since he's an experienced baker.
So he baked it himself thinking it was an extra effort
showing his love for his friend.
But the unexpected happened.
The cake was not done well and it was ruined.
The birthday was celebrated without a birthday cake.
The question is:
​How should the celebrant feel after losing a birthday cake?
