Happiness

Every morning, <font style="background-color: yellow;">I</font> <strike>would</strike> leave home early to read some English downstairs of our apartment building before<font style="background-color: yellow;"> i</font> go to work. Sometimes<font style="background-color: yellow;"> i</font> <strike><font style="background-color: yellow;">could</font></strike> come across the three or four year<strike><font style="background-color: yellow;">s</font></strike> old little boy.<font style="background-color: yellow;"> </font>His grandpa held his hands and walked him to kindergarden. He is a little plump<font style="background-color: yellow;">,</font>  <font style="background-color: yellow;">and</font> that make<font style="background-color: yellow;">s</font> him walk like a baby penguin. Anyway<font style="background-color: yellow;">s</font> he looks very cute.
Today, he walked<strike><font style="background-color: yellow;"> through</font></strike><font style="background-color: yellow;"><font style="background-color: yellow;">(maybe</font> you could put "toward" or ":into" here)</font> me and stopped <font style="background-color: yellow;">and</font>  said "hello! good morning, I am going to school". I smiled at him<font style="background-color: yellow;"> and replied</font>, " oh? Have a good day." I dont know why but his this one sentence just made me so happy.
He <font style="background-color: yellow;">made</font> me <strike><font style="background-color: yellow;">think that </font></strike><font style="background-color: yellow;"><font style="background-color: yellow;">(wonder</font>)</font> what<strike><font style="background-color: yellow;"> is</font></strike> the difference between children and adults<font style="background-color: yellow;"> is</font>. Children like looking at the world in a curious and intersting way and treat strangers naturally which <strike><font style="background-color: yellow;">our </font></strike>adults can't do. <font style="background-color: yellow;"><strike>Since when we cant do these anymore.</strike>(I don't understand this sentence)</font>
      Maybe when I get older<font style="background-color: yellow;"> I will</font> not be sensitive to<strike><font style="background-color: yellow;"> feel</font></strike> happiness any more. I would<font style="background-color: yellow;"> like to have</font> <strike>want</strike> a child. I believe he or she would teach me how to feel happiness from every small thing <font style="background-color: yellow;">that </font>happened in our lives.

 

--here is the corrections, the yellow is any changes that I made, and the line through the words are words you don't need in the text. Also I added some words to allow everything to flow better. hope this helps! :)

It is referring to a given "time frame." For example, I can say to my boss, " Can you give me a blanket period for the presentation on Friday?" And he could answer saying, "Sure. Can you have it ready by next week then?" I hope that helps
