Unexpected surprises and unintentional mistakes

5:09

an

5:09

unexpected surprise so again you can see

5:13

right a surprise by definition is

5:15

unexpected so you don't need to specify

5:17

that it's an unexpected surprise an

5:19

unintentional mistake mistakes are

5:22

unintentional that's part of the

5:24

definition of the word mistake they're

5:26

unintentional so we don't need to

5:28

specify it and to go down south or to go

5:31

up

5:31

north south is considered down right and

5:34

North is considered up again many people

5:36

say this many people say to go down

5:38

south or to go up North but technically

5:41

it's toogy and it's not necessary to

5:44

specify both it's one or the other to go

5:46

up to go down to go North to go south

5:49

but altogether it's redundant and we

5:52

often see examples of tautology when

5:54

we're using abbreviations so we when we

5:57

use letters to represent words because

5:59

we may not know or we may forget what

6:03

the last letter of the abbreviation is

6:06

representing so for example when we say

6:09

an ATM machine we're really saying

6:13

machine twice because ATM stands for

6:16

automated tele machine so it's like

6:18

saying an automated tele machine machine

6:21

also with my PIN number I've I've

6:24

forgotten my PIN number pin is personal

6:27

identification
