Nipped round to one of my neighbours yesterday to return something I had borrowed, ended up having a bit of a chat and was gone for about 15/20 minutes.
Came back to a message on my house answer phone and a message on my mobile voicemail from school asking me to call them back urgently.
Rang back in a panic, they wanted to give me a message about after school clubs last night.
Drop the kids off this morning and get a massive lecture about taking my mobile phone with me everywhere I go.
I take my phone if I'm going out-out, but not to nip round the neighbours/pop to the shop/run to the post box, etc.
I'm not always contactable straight away anyway even when I do have it with me, I can't be the only one who doesn't glue their mobile phone to them every time they leave the house
