My younger sisters are twins. It's nice to see that one has each other all the time (even though they argue all the time

) and just them being together always arouse interest in other people (a lot of my friends and teachers were asking about them). Everyone thinks it's fascinating. I don't think they're compared to each other. They both have different personalities and interests, they both have different ways of speaking, thinking etc. Fun thing is also, they are recognizable for all family members (they have a very little different facial structure), but for other people they look the same.
But no, i'd not like to have a twin. I like it the way it is.
