She was certainly making a big show of it, tutting and blowing up at her fringe.
This sentence describes someone who is clearly showing her frustration or annoyance in a very visible or theatrical way.
Here’s a breakdown:
"She was certainly making a big show of it" – She’s exaggerating her reactions, possibly to get attention or to make sure others notice how upset or inconvenienced she is.
"Tutting" – Making a tut sound (a quick click or "tsk" with the tongue) to express disapproval, irritation, or impatience.
"Blowing up at her fringe" – Puffing air upwards toward her fringe (bangs) to move it out of her face. This is often a small but dramatic gesture of exasperation or frustration.
Overall meaning:
The woman is being performative in expressing her annoyance—she’s not just annoyed, she’s making sure others can see it by tutting and puffing at her hair in an exaggerated, almost theatrical manner.
***
In the sentence, "fringe" refers to the front part of someone's hair that hangs over the forehead—what is often called "bangs" in American English.
So when it says "blowing up at her fringe," it means she's blowing air upward from her mouth to move her bangs out of her eyes or off her face—likely in a huffy or irritated way.
It’s a small gesture, but it adds to the overall impression that she’s annoyed and wants people to notice.
