Is it rude to put an exclamation mark after the word no?
It depends on how sensitive the person is, if they are sensitive then you shouldn't put an "!"
I don't think so !
Nope! Just add a smiley face! :D
no! haha see im not being rude
Not really. It just gives the impression that u put emphasis on it, as in yelling.
its not rude, but its a tiny bit irritating i guess xP
no, it's not unless you make a little angry speech to go with it.
In writing exclamation point serves as raising your voice or extreme excitement. If you are texting, this could easily come across as rude. Before you use it, read it back and ask yourself if the sentence were meant for you, how would you take it.
Not at all,
No, people are way too sensitive.
If you are emphatic, it is very appropriate.
