When two people share the same blood type and genetic material it is not ensured that they will be exactly alike, as it is true for my sister and I.
I think, this is self-evident and true almost for all people, except twiling perhaps. Even they are not completely similar. So, this is not the original sentence to start with an essay.
Start a new para here:
First of all, not only does a 9 year age gap differentiate us but so does how we look.
Secondly, we are very different in behavior.-this is the second para.
I have always been a fast learner and very goal oriented;
as long as I remember my goal has been to be a
successful architect, to built many homes and get recognized by people, nothing has been able to stop me.
While My sister, in contrast
, has always had difficulty learning and can't concentrate on a goal long enough to achieve it,
and worst of all, she gets put down easily.
I will always support her;
isn't that what older sisters are for?
Finally, we have very different likes in almost everything, from food to entertainment. - the third para begins here.
I could say this loudly and my sister will be proud of it:
she loves food.
I am a vegetarian and believe that anything in its raw form is the healthiest. I don't
eat out because I can't control what the cook does and don't eat
My parents prefer taking my sister out to eat rather than
When it comes to music it is the most complicated part in all,
since she likes
No matter how different we might be we will always be alike because thanks to our parents we share the same blood and genes.
Again, not the best sentence to end up an essay. All the more, you have mentioned blood and genes in the beginning. You may say it different, like: No matter how different we might be we will always support each other, as we are the family. or: No matter how different we might be we supplement each other as differences bring us closer.
