Our conversations kindof go like this...

(on trip back from music class-abridged):

G: walk, walk, walk! (bobbing side to side)
M: Yes, you ARE walking.
G (beaming): YES!
G: Flower. Yellow Flower.
M: And what color is that flower?
G: Purple!
M: That's right!
G (standing next to the sidewalk, pointing down): Grass! Green grass!
M: Gilly, you have to hold my hand to cross the street. Ready?
G: Car. Gilly Boom! (giving me her hand; this reply showed me she remembered the reason why I make her hold my hand when we cross the street (cars can hit you and make you go boom, which I had told her several weeks before that and which we had not spoken of since-I found that interesting))
(train passes by on the elevated track)
G: CHOO-CHOO!!!!!!!!!!!! CHOO-CHOO!!!!!!!!!! More? More Trains?
M: I bet there will be in a minute. It's rush hour. (and there were lots more)
G: RED car! (one favorite walking game is "what color is that car?")
M: Yep.
G: YEP! (nodding) YES!!
G (sitting on a building entry stair): Mama, sit?
M (sitting): Taking a rest?
G: Aye.
G: Doggie! White Doggie!
G: Mama's shoes. Gilly's shoes. PINK!
M: Your shoes ARE pink! Ready to go?
G: Aye.
G (pointing): Flower! (picking flower). More flowers (picking more).
M: What color are your flowers?
G: WHITE! and GREEN flowers!
M: Yep.
G: YEP!
G: (singing song from class and moving her arms while stomping): Go, Go, Go....STOP!
M: We're gonna go, go, go, we're gonna go go go, we're gonna go, go go and.....
G: STOP! (laughing and jumping during the exclamation-this continues in varying speeds, which she adjusts her arm and stomp motions for)
(I grab her Elmo and run up to the corner of a building ahead and hide, letting Elmo peek around the corner at her)
G (delighted): ELMO! Peek-aboo Elmo!
G (holding Elmo and putting her hand over his face and taking it off): peek-aboo! Peek-aboo! Peekaboo ELMO!!!! Hand? (taking one of Elmo's hands and giving me the other, so we're walking down the sidewalk holding his hands)
G: one, two, wheeeee! (swinging Elmo like we swing her when we are both holding her hands)
M: Wheee Elmo! Want to go again?
G (emphatic nodding): Yes!
M: one, two, threeeeeee!!! Wheee!
G (laughing): Silly Elmo!
M: Silly Gilly!
G: We're home!
M: Yes, we are home.
