Always add acid to the water.
Otherwise the acid can get on your skin and hurt you.
Always add the acid to the water.  
for as you try to dilute it, a lot of heat should be generated and the larger volume of water should be able to absorb that heat.
Always add the acid to the water.
But
She's  always the water and you're always the acid.
notwithstanding the facts,
She is always trying to pour herself unto you.
Knowing what unwanted reactions it might bring
She still tries to add herself.
Trying to make yourselves match;
always believing you could have the most perfect reactions
and
All she has was an illusion.
For
Water in acid should never be done
because Acid in water infrequently goes wrong.
Now
She's terribly hurt.
Can't escape from what the solution brought.
