Well not the street but in my back garden by the gate.
Mornings tend to be a bit hectic here, so I usually get DP off to work, get the eldest DC out the door to school,give the baby his breakfast then grab a shower and get dressed myself, so at 8:30 this morning I was still in my PJs and dressing gown when I heard a clanking in the back garden. I opened the side door to find a man standing next to the shed, rooting through a pile of junk. We are having the kitchen done, so the old units are there until we can fit a skip in and there is also the old fuse board in there which is what I assume he was trying to get to. I heard more clanking so looked toward the back gate only to see another guy carrying my sons' seesaw and the legs from our patio table towards his van. He was already halfway out of the gate and I'm afraid I panicked a bit and shrieked "Noooooo!" and started towards him. The guy by my door tried to block my way and started saying "sorry sorry sorry, I knock you door, you no answer" while still trying to look over my shoulder at the heap of junk.
Now I'm afraid at this point I lost it a bit as a) I know full well he hadn't knocked as I was in the dining room which the side door opens from for 10 minutes before hearing the clanking and b) his mate was still trying to juggle the table legs and seesaw while now trying to open the doors to their van. I stormed down the path, asked him once to put my stuff back in my garden and leave and when side door guy wouldn't get out of the garden I got progressively more and more shrieky. I was waving my arm, pointing out of the garden and yelling loud enough to get a few of the curtains opposite twitching 
For the sake of clarity, scrappies going round doing collections from houses are pretty common round here, I often see 3 or 4 vans a day. I am new to the area and where I used to live didn't have people coming round picking up scrap so i was curious about it and asked around. It turns out the scrappies are licensed and have to abide by certain rules, such as asking permission before taking anything and only coming onto the property to knock and ask permission. I may have yelled that I was going to get this guy's license pulled if he didn't get out of my garden now. He didn't seem that bothered so I am wondering if he was in fact licensed, as he did jump in the van and bugger off sharpish when I started taking down his van reg.
DS2 is now mortified that I was out in the garden in my garish bright pink fetching dressing gown and making so much noise that the neighbours were looking. He left for school with his hood pulled down low in case anyone saw him. Was IBU to have flapped my arms around like a demented flamingo at half 8 in the morning? Will I be forever known by the curtain twitching brigade opposite as that shrieking harridan?
