I actually have a piece of the Berlin wall Not huge but a piece nevertheless.

Before the wall... Bad.. depression then defeat in WW2 then Russian control and tension with west.

During the wall... Bad.. lotsa ppl trying to escape, getting shot at... communism not working... trabants height of car design ... some bad australian band writes "they built the wall not to keep us out but to leave no doubt they're out of order".. maybe was little river band

After the wall... Bad ... High unemployment .. resentment of wealth in the west ... continuing ostracization of easterners

So, in summary it is all peachy keen Hope u get an A by quoting me
