are you kidding me

So I come home from a LONG day of work, school, and work again to find my cute roomie making us dinner. She was cooking rice with veggies which I love love love! Our FHE group was meeting at our house and dinner wasn't going to be done for another 20 minutes so I decided to turn on Fox News and eat some tortilla chips while dinner was cooking. So I'm just sitting there minding my own business when a girl from our group comes into our apartment, says her hellos, walks into the kitchen and proceeds to get a spoon full of rice then sprinkles some veggies on it without even thinking twice. I'm sitting there thinking who the freak is this chick?! THEN, no joke like 3 minutes later, a guy from our FHE group walks into our apartment, sees the chips sitting next to me, picks them up and then helps himself. I guess I gave him "my look" because his face went red and then he said something like "I can't believe I just did that." Ok people, I don't know you but you feel comfortable coming into my home and eating my food. My other roommates don't know these people super well either....where were they raised? People are weirdos!
