What is the difference between この and こちら/こっち
(こっち is the informal form of こちら)
The definitions my book provide are as follows:
(この = This)
(Example = (この子 = (This is) my child))
(こちら/こっち = This(person))
(Example #1 = (こちらは本堂さんです = This (person) is Mr Hondou))
(Example #2 = (こっちは家内です = This is my wife)
