Silent-type people are dangerous and unpredictable, agree or disagree?

I'm a silent-type person and usually when someone asked what kind of person am I, they say I'm quiet and silent but there was one person who actually commented that silent type are very dangerous especially when angry. Bulls-eye on that one. I'm very scary when I'm angry and I can really hold a grudge for years, the truth is I'm even scared once I'm angry and as much as possible I tried not to get angry so I tend to keep all my emotions in.
