Sneaky phone call

Connor made a sneaky (unauthorised) phone call home last night in response to a text that I'd sent asking how he was getting on.  I'd only sent a text because I thought it would be pretty inocuous and that he could respond as and when he was able.  The signal was pretty awful and I could barely hear him although I heard enough to realise that there is some problem with his boots - he has to have them made specially so he doesn't have any yet and doesn't know when they'll arrive.  This seemed to be quite a concern for him for some reason but I couldn't really get to the bottom of it because the line was crackling and breaking up as he was trying to talk to me.  He said he'll be in touch again when he's allowed another phone call.
