We would always eat the fish we would catch
Oh, OK. Is there any reason why you are bringing up this memory?
Yes, my elder brother would always eat my share of fish
I'm sure the fish looked very tasty and delicious, but it was very wrong for your brother to eat your share of the fish that you caught. Next time that you would go fishing with your brother, I would recommend that you set boundaries about your share and how it is not okay for him to eat it.
You are making a big deal out of nothing; we're just kids.
Still, it's wrong of him to eat your fish. If you can get him to stop doing this now, he is less likely to take advantage of you in other ways later in life.
