Am I selfish?

So I was just told I am selfish because I wanted to cook me some shrimps that I had bought. This is the only item that I have in the house that I have bought and it was just something that I wanted for myself. Last time I bought shrimps I bought almost three pounds and made them for my family (two other people) I even bought fries and just cooked the fish we already had. But am I selfish for just wanting to have something for myself that I bought?
