Let me guess - you're a teacher.
I'm just going to come out and say this - can't teachers realise parents are busy too. Oddly enough you aren't the only people who are working hard and may be busy early in the morning.
Parents around here often are off to work in the wee hours of the morning (many work hospital shifts or have long commutes here) - so in fact it is very common that the parent will remember well after leaving for work that they need to tell the school something (doctor's appointment tomorrow/ can't pick up send them to after school club tonight/ ex-DH is picking up children tonight, etc....).
Several parents are surgical nurses and frequently due to the nature of their work miss pick-up times so text/ e-mail school (often directly to teacher) to notify them of change of plans and what to do.
Our school also uses a group text system to let parents know things (e.g. Year 1 will be arriving back at school from field trip around 6:30 p.m., etc...).
Personally I find if I have a query (bordering on complaint) having it in writing is jolly useful. It provides a record that I've raised a reasonable query & politely and means the teacher can't say otherwise - I've stopped having chats, because of how bristly and defensive the allegedly 'professional' and 'dedicated' teaching staff at our school have been, when it really is quite reasonable for any human being (let alone a mere parent) to query whether books will be sent home this year or not? After all it is October 10th and nothing has come home yet? (hopefully this hasn't outed me - but that was the content of today's e-mail)
