tornado

could not get it to rotate and save tonight. last night, after hearing the radio announcement regarding a tornado watch she

*sits down, draws a picture of a tornado with a very large circled "no"
*comes back and writes (quite well) "I hope not"
*watches tv, sees some pictures and returns to write "it hapind" (think fo-net-ik-lee)
*watches tv until storms have passed, returns to cross out previous two stages and write "it's ovre"

what i want to know is how she knows it's is spelled it's.
