how to deal with your siblings...??????

My little brother, I always take good care of him ,and we have no stinging arguments.

I am older than my sister by 7 years (I'm 25 and she is 18) - we have always fought (by that I mean argue never physical fighting). We just never had anything incommon because of the age difference. Though as she is getting older we do fight more but we also have more moments where we can talk on the same level. Like girl things and relationship stuff that we could sahre before simply becuase she was too young to truely understand. I'm sure we will continue to fight - we always to things to annoy one another - actually kinda like agame, childish yes but it is my baby sister.
