Hi all Buddies,

Am so delighted to have your prompt guidance. So thankful to you all. Today again I am sending some querries for your kind attention.

Two years
ago, I visited my home town, which I had left two years before.
1). Why two years period repeated in the above sentence ... Did I leave 4 years back or what ?

2). To understand this sentence, can I rewrite as below...
In 1996 I visited my home town, which I had left in 1994.

3) Please assist me for / with (should I use for or with ??? ) difference among Ago / Before / Back ???.

Thank you members

2). To understand this sentence, can I rewrite as below...
In 1996 I visited my home town, which I had left in 1994. - Yes.

3) Please assist me with the differences among Ago / Before / Back.

As we are considering those words here:
Ago = before now.
Before = back
