Hi! Do you think brothers and sisters should necessarily get along?

my brother and sisters live each in a different part of the world and we are not frequently in touch though we've never had any quarrel. However me, being the youngest; i wished to get to know them better so i reached out through email and sms. At first it worked and everyone seemed happy with it, but after a while things got like it was before. so now am fed up as well. What do you think of it?
