You and Sigma are old classmate . One day , you got an invitation to participate in the class meeting after 5 years graduated. You got there , the meat grill restaurant , enjoying the party but didn't eat much , you only do the grill work. Sigma saw that in the corner of his eyes , grabbing meat into your plate.

-" You should eat more , you only grill the meat all this time , let me do it"

As he said , he continues to put more meat into your plate
