person A: I stepped in gum someone spit on the side walk today.
person B: Were you able to get it off of your shoe?
person A: Only some of it. 
person B: Keep working at it_comma_ you'll get it all. Try ice on it to harden the gum first.
person A: That's a good idea.  My biggest problem was trying to get most of it off with nothing on me.   I had to drive home and didnt' want gum all over my truck
