I did the stupidest thing once by giving my home #. Lord have mercy! I couldn't stop getting calls from the parent: "Ms. does Juan needs to have homework # 1 or 2 done? I don't understand why Juan got a C. Explain this and that to me please so I can tell Juan. Did Juan misbehave in school today?" Oh how I have learnt my lesson. Do you give out your home #, mobile, or email address to parents and students? If so, had any bad/good experiences with any of the point of contacts? I would give out my email address ONLY and only in extreme circumstances, I would issue my mobile to the parent.
