PRE-TRIBBERS Please Explain

I have never understood the pre-trib position on these two chapters. To me they both indicate that the rapture occurs at the second coming after a time of trouble, I would just like pre-tribbers to explain how they interpret the texts. I generally believe the bible is better understood taking the more obvious reading of the text because it wasn't written for rocket scientists and Greek scholars, and so I'm really interested what you have to say:

This seems to be saying that pre-trib believers will get their relief/rest at the second coming on a day of vengeance and punishment for the ungodly:

2 Thess 1

we ourselves boast of you among the churches of God for your patience and faith in all your persecutions and tribulations that you endure, which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer; since it is a righteous thing with God to repay with tribulation those who trouble you, and to give you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ. These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power, 10 when He comes, in that Day, to be glorified in His saints and to be admired among all those who believe

This seems to be saying that gathering of pre-trib believers and the second coming are the same day of Christ, and only occur after the man of sin is revealed:

2 Thess 2

concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.

What say you pre-tribbers on these two chapters?
