simplistic first borns

to me, first borns are simplistic, impulsive and more innocent than the other siblings... and no, this is just not autobiographical (yes, i am a first born), but also borne out of what i have seen in many other families, my marital family included...
first borns tend to be more attached, more sentimental, more adjusting...
they adjust and accommodate when a sibling or two comes, while the latter borns arrive when the first borns are already there...
possibly because born when the parents are relatively younger, less mature, first borns are impressionistic, take time to grow up, while the latter ones are much more worldly wise, mature faster and give a lesson or two to the elder sibling...
first borns also get flustered easier and faster compared to the latter... they have a lower threshold level...
their capacity to love is more, they also tend to be less selfish... many a times, they tend to carry on traditions which have little value for the latter borns... they also have a deeper connection with the wider family... since they come at a time when the immediate parents have stronger ties with their family at large...
parents' expectations from first born is always more... they give up with their latter borns... they learn with them, but with the first born, they are much more harsh, much more expressive, much more demanding...
given all of these, i would still want to be born first to my parents since it is then i who will be the first to give them a new identity... call them Ma and Pa...
