ASV notes on Genesis 3:8-13
God went down to talk with Adam and Eve as usual, in the cool of the day, normally they would be in the open and easy to find, but this time when God came they were afraid and had hid themselves behind some trees or bushes.
In the presence of YAHAWAH you feel inner peace and secure, you know that He is the one that takes care of things and looks after you.
But in this case with Adam and Eve eating of the fruit of Good and evil, all the responsibility was suddenly on their shoulders, they had to perform and present themselves. They could not go around in the garden naked and they had to defend their actions.
Adam blamed the woman, the woman blamed the serpent, and they knew they were in big trouble, but they didn’t know what they had done to the rest of the mankind. I think God felt sorry for them and saved them from explaining to them the devastating result of their actions.
