3 things that make me upset

There are two things that I get irritated. First, A surrounding sound is noizy things when I am studying a subject. I am doing club activities and the byte. Therefore the studied time is limited to me. because time is even one second important. The studying time of a subject want to do quietly.
Second, There is thing that the signal is often change to red when hurrying up. The reason is that it might be if the signal was waitting of change.
I am gentle man. Because I do not get irritated so much.

Technology

I use various technologies every day. I am using cell phone most in technologies. The cell phone is used on mail, telephone, camera, and Internet, etc. The advantage of the cell phone is very light, and is convenient carry and walk. But, when cell phone have no more the battery because it is rechargeable. The technologythat I am not good is a personal computer. I reason that becouse used of cell phone had spread, personal computer did not use it on mail and Internet, etc.
I think that life became rich compared with old times by the technological improvement.
