non-vegan family

My aunt gave me a few non-vegan xmas presents. She lives far away and I don't see her often. She's very nice and we get along, but because we haven't spent much time together, we aren't close. She comes from another country from me where vegans aren't very common. I was vegetarian for years...

My brother, who is three years younger than me (I am a teenager), seems to be very close-minded when it comes to the reasons for being an ethical vegan. He doesn't understand how the milk, egg, honey, etc. industries are cruel and often asks me why, so I give him a logical and clear explanation...
