Cousins are siblings

Ever since I was little, I lovingly called my cousins 'sister' or 'brother.' Not until I went to the US when I realized that there is no Chinese word for 'cousin.' As an only child, I'm thankful that I've experienced a special bond with my cousins very similar to siblings (I can only assume). Pictured are 1) cousins on my mom's side and 2) cousins on my dad's side.
