when will the questions end?

Here is a sample of some of the questions my 3-yr-old asked me this week: What kind of knife is this? (A green one) What kind of trees are in the woods? (ummm, pine trees maybe) Why is baby food in jars? (Because otherwise it would be more of a mess than it already is) Do grapes come from grape trees? (No, grapevines, like the song, "I heard it through the grapevine") What is a vine? (they are like this thing (me pointing to a plant)) How many minutes until we get there? (1 minute) How many minutes until we get there? (1 minute) How many minutes until we get there? (59 seconds) What shape is my poop? (Poop-shaped) ...And that is just the tip of the iceberg.
