But

"But I received a raw deal and deserve to be treated better"
You can't make demands anymore.
"But I was at the receiving end of this unfairness
You don't have any rights to ask for anything.
"But didn't it mean anything at all?"
It belongs in the past.
"But I didn't want it to end"
Too bad. It did.
"But, I want things my way"
Everyone does.
