Some by Today Hi. Today I have been some tired, this should be because in the last days I haven't done almost nothing. I often be very busy; I usually study, do my professional practices and I move of side to other, so I am always doing something. So I wanna to say that I have been very bored by this days, I believe that need begin to spend my time in a lot of activities. I well, perhaps some of you wonder Why this man say be tired, if himself tell that haven't done this days?. Ok I know that this seem strange, but I think that this may be so. Some days ago I heard a person speaking about of when a individual is accustomed to doing many thing and stop by a moment some long, people are tireder that when are doing your own activities. May that in the first days the people rest and feel fine, no all is work and study, this is well but I am sure that the teory of this person is really correct. I wait your comments and corrections. Thanks you very much by read.

What happend today? Ok, today has been a interesting day. Because, I have visited a lot of web page and I have enjoyed learning about the differents expressions that are used in language English, and despite its translation don't seem correct or wanton, its mean is wholly different, is like a "dicho" here in Colombia.
