The Expired Sardines

I live in a boarding house for months and I always eat outside, in fast food chains and the likes. But one day I didn't have enough money to buy food so I open my last resort—can goods. As I eat it I notice it's not that reddish as it was before and it's salty. I thought it's a new flavor but when I looked at the can's information it already expired months ago. So the lesson here is always check the expiration dates or else you'll experience lbm!
