I imagine without wireless technology it so very hard when two people meet in one place. it's so hard because they could't see each other becase there's no wireless technology they cannot communication is back to old style using the service of postal office ..and when an invitation of an occacion it so hard because we will use the postal office or we will go there to said that they must go there..

I imagine without wireless technology it will be hard to many people becuase we will use the service of postal office to get that letter to them.it will get there 1 month to recive that letter ..
