I can do live without mom...she is the most precious human and is like a gem 
I think the answer for me would be my friends because my friends help me a lot in all the things which are related to me like studies and sports. if my friends were not there I would be nothing in this life. they helped me in achieving many things also. my friends are really precious like a diamond. my friends are not like the autumn leaves that be every where they are like diamonds which are rare and useful. my friends make my day, my friends would even help me in completing my notes on time and doing home works also :)
