I caught cold...I have a pain in a throat, and there is some heat.
I stopped at CVS between a couple of meetings at the Silicon valley. There is huge medicine on a shelf and it is not easy to select appropriately one. Then i spent time more than I expected just for picking up one item.
It may be that language knowledge to be usable in such situation is the most important skill who has to live in foreign country.
In other words, it is used in the serious situation to sometimes occur, it does not occur every day.
Fortunately my choice was correct and it seems remove my cold.
