How much is the weight of glass of water ??

  It is the class room.

Students were waiting for their teacher to come.

Teacher entered the class holding a glass of water. 

Everyone were anxious to know what is happening ?

Teacher came inside the classroom and kept the glass of water on the table.

Teacher asked the students, 

Can anyone tell me what is the weight of glass of water here  ??

Everyone started telling different answers.

Teacher silenced all of them. 

Teacher said, 

I am not talking about material weight of glass of water.

Whatever you have said the answer, that could be correct. 

Suppose if you hold the glass of water for a minute, it may feel light weight.

If you continue to hold it in same position for 5 minutes, you start to feel its heavier than before. 

You feel that same glass of water is getting heavier as the time passes. 

Finally you feel like it's better to put it down. 

Similarly ,  in a relationship if you find it toxic, give it some time. 

But when it is hard to be in the relationship, just leave everything and come out of it. 

This is the similarity between relationships and this science experiment.
