I would say the answer is because they are in fact older.
most families would even rely on the older sibling to babysit. and because of this they come to think of themselves as the boss. Sadly in some cases the older sibling does indeed become the boss enforced by the parents. which really should not be unless there is a significant age and maturity difference. if the older sibling is only a few years older they really shouldn't be an authority over the other (except in babysitting situations) especially if the older sibling isn't all that much more mature than the younger.
Hope this Helps.
Because little brother knows the difference between their/they're and then/than.
Obviously NOBODY KNOWS WHY,but I think its because they wanna be smarter than you,like when your a big sister and have a little or big brother they try to be smarter better than you......and I hate it even though I know IM THE SMARTEST!:D
You accumulate more knowledge, have had a lot more experiences, and you start to think.
Rihanna has 2 brothers and Rorrey is 20 almost 21 and Rajad is 14.
Blake I think
No she has three older brothers I think.
older brother i think
nature loving 'cause if a older brother has a dragonfly sit on their finger they want their sister to be happy or he would smash cause he wants her to feel sad?
I think she has three older brothers, one of them is called Marcus.
Yes. Jennette McCurdy has 3 older brothers, Scott, Marcus and Dustin.
To me I think they are about 6 years and younger but some 6 year olds are smarter and you will find them a little more mature than older kids.
i think 3...
The Brothers Grimm I think.
