A good sentence to end my essay?

As the sun above Thomas' head hit the zenith, the air turned so thick, one could almost taste all of their pride and joy.

I would rewrite the penultimate sentence this way:

All who were close and supportive of Thomas J, notably his mom and the others-with bodyguards in tow, witnessed his graduation ceremony.

The final sentence:

A seemingly simple event, This achievement proved that even the sky, has no limitations.

I don't like to see parts of the same word used more than once in a sentence. Graduation and graduate are redundant. I don't know how the people listed are used in your essay, but I would bet that the reader would know who they are. Therefore, most of the names can be excluded.

Leave it like that. Except put ......... <----- at the end of graduate. so.. its

In the day of the graduation, Carlie, Harvey, Mr.Garrason, Mr. and Mrs. Mason, his mom, and Carlie's bodyguards went to see Thomas J graduate......

Your listing too many names, the sentence seems kind of awkward. It's kind of hard to end a story that you didn't write if we know nothing about it also, I think only you can do that.

Thomas' friends and family and his families bodyguards arrived promptly on the day of Thomas J's graduation to see him graduate.

thats how i'd rewrite that sentence, but once again its hard to think of something to write if we know nothing of your story and how the characters relate to the main character.

Everything turned out the way Carlie wanted and she continued through the path she chose.

Everyone present allowed their emotional guard to drop, freeing a celebratory river of tears that drowned the emotions of the now forgotten past, and to carve a fresh path of promise into the beckoning future.

No only some live. The body guards all die Only Mr Mason dies saving his wife. She donates his pension for a scholarship

Always leave the reader wanting more. However, this sentence shout support your thesis of the essay. Make a point of what you want to say.

you could say something like. Now that you've read this you should want to recycle. or do you see now what not recycling does to the community? Recycle for a better future.

u can say one of my personal favorites:

time goes by,people change,life goes on

just modify it to better suit ur strategy eg.change the tense or make some of the people u mention say it or something like that ok?
