I\'d like not to have a twin.

The reason why I don\'t want to have a twin is that I don\'t want to be compared with my twin. It\'s not about getting siblings, I mean. If we, the twin and I, are similar, many people around us will confuse who is who. Also, when I do something , they will think, \" oh is that she? or her twin?\" I don\'t like want to confuse others. but In different ways, I like to have my siblings. because it is fun to play with them and have many days going traveling or shopping with them. But our age term is so long.( I\'m 30 and my brother is 19) So I used to think how would it be if I would have a brother or sister who is older or younger than me just under 2 years different)
