Is it practically possible?: 

'Liking everybody or everybody liking  us!' 

These are all quite possible!: 

'Liking somebody or somebody liking  us!' 

'Not liking somebody or somebody  Not liking us!' 

Things to be worried: 

'Not liking everybody or everybody  Not liking us!' 

There are plenty of reasons, 
for all the above 'LIKINGS'! 

I won't advice to analyse the reasons for, 
"Why I don't like somebody?" 

I would like to suggest that, 

'If somebody doesn't like you, 
let them be... 
Don't try to convince them!' 

'If somebody do like you, 
like them more... 
Don't try to spoil it!' 

'If you do like somebody, like them  wholeheartedly... 
Don't try to move away from them!' 

'If you don't like somebody, let you be... 
Don't try to move towards them!' 

These are all beyond the reasons! 

Let our heart decide, 
what to do!
