Color can affect how we feel and influence what we think. In general, bright bold colors tend to stir us up, while the softer pastel colors calm and relax us. Responses to colors can vary by age, gender and cultural background.

I can think about some things that are always annoying: Wait for a person that always arrives late to meetings; that my computer comes up to an error before saving the job I've been working on for a long period of time; spam emails.

Even though, there's one very worse than those mentioned and it's an outdated website. Let's say I get a flyer of a company with a product or service that I interest. The first thing I do is write down the website and throw out the flyer (why put away more papers?), when I go to the site to know more about the company, just there start the problems.
