Are you also Trigger when your friend use a specific emoji ?

I have a friend whom I adore and cherish dearly. But I hate chatting to her on the internet. The reason? This smiley:😅 . She uses it at the end of every sentence like a dot. And I hate that emoji so much. For me it’s like she finishes a sentence with expressions like: “you’re stupid”, “that’s silly”, “it’s so obvious”. Because that’s what this smiley represents to me.
