"We did it!"

• Tony will say "We did it!" after something has been accomplished,  whether by him,  or by another person, or by him and others.  He picked from the expression from a show called Dora the Explorer where, I guess, they don't say "I did it!" or "you did it!"
• Tony took his new toy, the red fire engine, with him to school yesterday.  Dad was relieved to see the toy in Tony hands at the end of day.
