Dear Classy T,
The Bible doesn't say that we ARE absent from the body, it says that we are WILLING to be absent from the body and with the Lord. This is not a reference that even has anything to do with death, but rather, it has to do with living in the flesh versus living by the Spirit (the Holy Spirit). Being "with the Lord" here means that we are to live not in the sinful state, but to live lives in the Lord.
Here is a link that will describe this in more detail, so you can understand it fully:
"Absent with the body, present with the Lord"".
In Christ,
Brenda
