i lost my safari icon and can't find it on my imac. how do i reinstall it?

Often when people think they've deleted an application, what's really happened is that they deleted its icon from the Dock. In the Finder, select

Go ▹ Applications

from the menu bar, or press the key combination shift-command-A to open the Applications folder. If the application is in that folder, drag it to the Dock (not to the Desktop or anywhere else.) The other Dock icons will move out of the way to make a place for it.

Well, after a few hours of trying to resolve this issue I am embarrashed to say it was there in applications all along. I did not realize I had to scroll down to see the rest of the icons. I thought all the applications were showing. Ok you can laugh, I am still laughing. I think I do well for a 70 year old..
