The use of 'common'

I am trying to say something and I think I should use 'common'. But, after looking at a dictionary, I don't think that 'common' is the approriate word.

This is a situation: after knowing that her boyfriend is walking with another girl, she [my friend] is angry with him.

Now, I want to tell the situation to another friend: "It is common that she is angry".

I don't think that 'common' in this context is true. Can I use another way?
"No wonder that she is angry".

Thank you for your help. I hope that my English is enough to be understood.

Perhaps understandable, reasonable, justifiable, excusable, fitting, rightful?

It 's obvious she is angry. It stands to reason that she is angry. It is self-evident that she is angry.

Surely still more choice.

I would personally use the term;

"It's understandable that she's angry"

.......for the context you want.

The others are also technically usable but [no offence Claude!], I certainly wouldn't use the term "It is self evident that she is angry" !

Thank you for your help.

Why does the British call their parliament 'The House of Commons'?

<<Why does the British call their parliament 'The House of Commons'?

The British Parliament is actually comprised of two houses: The Upper House, known as the House of Lords, and the Lower House, the House of Commons.

The full, formal style of the House of Commons is The Honourable The Commons of the United Kingdom of Great Britain and Northern Ireland in Parliament Assembled. The term "Commons" derives from the Norman French word communes, meaning "localities."
