During Jesus' Farewell Address in chapters 13-17 of John we discover Jesus doesn't have a very good short-term memory or attention span.
John 13:36
36 Simon Peter asked him, “Lord, where are you going?”
Jesus replied, “Where I am going, you cannot follow now, but you will follow later.”
Peter asks Jesus a simple and clear question about where he is going.
Later we read in John 14:5
5 Thomas said to him, “Lord, we don't know where you are going, so how can we know the way?”
Okay, that makes Peter and Thomas interested enough to voice concern about WHERE Jesus is going.
What is Jesus' response?
Read the follow up in John 16:5
5 “Now I am going to him who sent me, yet none of you asks me, ‘Where are you going?’
