What happens if I forgot to decline an offer?

[keisan89]

Hi all, I got admission from 3 US universities, and I accepted one. However, at this time I suddenly remind that I haven't declined one of the other 2 offers. Is there any bad things happens?

No, you didn't accept them either. Generally, you need to send in some formal acceptance. It is a bit inconsiderate not to notify schools that you are no longer interested in, as they generally have people on waitlists, but nothing bad should happen to you.
