This may be a really stupid question but DS absolutely loves diggers etc. We can't go past a building site or other type of workmen activity without him asking to stop and watch. Sometimes I say no if we are in a rush but otherwise I often stop so he can watch for a bit. Sometimes it is clear that the workmen are happy with this e.g. if they wave or say hello to him. But other times it's not clear and I wonder if I'm being unreasonable. Like, what other jobs is it OK for a small child you don't know to sit and watch you do it? On the one hand I think it's nice because he obviously thinks what they are doing is the coolest thing ever but on the other hand I feel like it might come off as intrusive. Am I overthinking this or am I being unreasonable by stopping to watch? Of course I could ask to see if they mind but that's not always possible and if I'm honest I feel a bit silly doing so. I don't want to interrupt their work!
