An Annoying Habit
One of the reasons he won her heart in the first place is because of the funny accents he can imitate. She loves them and they always make her laugh. He uses them during tough moments to lighten up the mood at it always works. But eventually, he got hooked and it became too much.
After two years together, her boyfriend still would not stop speaking in the fake Italian-American accent. Furthermore, he was making up words that she couldn’t even understand. It actually became pretty annoying. Hopefully, he will let her in on his secret foreign language so it could be “their secret thing”.
