It’s hard to believe that no one had computers a few years ago. There must have been a lot of paperwork. we can’t imagine writing everything by hand. We need computers today for everything. nothing can work without computers. I’m sure we’d be ten times busier than now if we didn’t have a computer. Imagine having to find a piece of paper and an envelope and then walking down the street to mail a letter! computer makes everything in our life so convenient.
