I just finished a long term subbing assignment, and had something kind of disturbing happen. A student on my last day got a hold of my cell phone and text messaged themself and thereby got my number. Then they sent me a "we'll miss you" message. I thought it was kind of nice, so I responded with "thanks" and now it hit me that I willingly text messaged a student. I have no idea what the policies or laws are on that since they give subs zero training. What would you guys do if you were in my position??! Should I go to the admin of the school and tell them about it, or should I just not worry about it? I'm terrified.
