emotions

[Unregistered]

if someone says something offensive and they don't realize it you can say that, or
in similar situations where one person is just unaware of the tensions.



I found this sentence above online. Why did the writer pluralize tension. What if I singularize it, what difference does it make?

You're making it more difficult than it needs to be. Was there one tension or many tensions?

When one emotion is dominant it's singular: 'I can't control my emotion at winning.'

When you're a mix of feelings it's plural: 'They struggled so hard and, against all the odds, they won. I can't control my emotions.'
