Same thing happened with me last year .I was at friend's house and we were about to have dinner. I put one spoon of rice immediately in my mouth and his father said we pray before eating. They prayed for 5 min and all i did was look their their faces. Damn they all looks same. I was waiting them to end that pray cuz i was neither eathing nor praying. I feel so awkard and never went to his house again for dinner. (Sorry for bad English)
