Birthday boy...

I just came back to my room after morning class.. and today is my special friend's birthday. He want to give me a treat and then to cinema... Unfortunately I have a very important class to attand and I couldn't miss it. I told him to postponed to the next day.. But, he said he can't because he won't be here tomorrow as he's going back to his hometown.. again and again he persuaded me. I couldn't think of any other option but to skip that class and went out with him...

in the critical thinking,i find ad populum to force when my friend persuaded me...
