It serves no purpose to get bent out of shape about it.
→ 기분나쁘라고 그렇게 한건 아닐꺼야.

[예문]
A: I received a wedding invitation via email.
    I’m not sure how I feel about that.
     이메일로 청첩장을 받았어. 기분이 이상해

B: What’s wrong with that?
    Everybody uses email and it’s actually a very efficient communication tool.
   뭣 때문에? 모두가 이메일을 사용해. 굉장히 효율적인 방법이야.

A: I agree, of course,
    but a wedding invitation should be more traditional and personal.
  맞아. 하지만 청접장은 좀 더 전통적이고 개인적으로 줘야 하지 않을까.

B: Times are changing. You’re probably right,
    but it serves no purpose to get bent out of shape about it.
    시대가 변했잖아. 네가 옳을진 모르지만, 기분나쁘라고 그렇게 한건 아닐꺼야.
