telephones

i have just realized that i have no clue what my kids cell phone numbers are. i have them stored in my cell and on the frig, but, until just now, i couldn't even remember what numbers they started with! does this make me a bad parent? i doubt it. i have no cell reception in the public library where i am working this week and they need to get up! sleeping until 1pm has to stop! school starts back on monday!
