Rear-ended gently at a roundabout

[dBfazer600]

Just started riding in the 80's and on a little YB100. Was at a round about waiting to join it. I had just stood up feet on the ground and bang. Bike shot across into traffic I rolled on the floor in agony where to two rear indicators slapped my hamstrings. Never found out who did it as they  :foc This was in broad daylight around 0800 as I was on my way to work but ended up in A&E.
