I AM SO HUNGRY ON MY GOSH

I AM SO HUNGRY OH MY GOSH. I hate that, when you're at someone's house, and you're dying of hunger. But you still want to be polite. So when they offer you food you have to be all "Oh thank you! I'm not even hungry! -insert polite laugh-" but you're really all "OH MY GOSH GIVE ME THAT FOOD I'M GOING TO EAT YOUR WHOLE FREAKING HOUSE." Society sucks. We all wanna eat. Why is it impolite to open someones fridge? I open mine all the time! Does anyone else feel this way? Or is it just me?
