This is the word of the day today!
At the end of our road is the main thoroughway and the hospital (where I used to work) is also only 2 km away, this all means we hear the ambulance sirens multiple times a day. Today when it was going almost continually around lunch time I pointed the siren out to the terrible two and that was that! "Ambulance" and "Bebah bebah" were being shouted everytime they heard the siren. Ciara and Enya know what an ambulance is as we watched a next door neighbour being loaded into one a few days ago (we don't know these neighbours but I don't think it was too serious as they didn't blue light it away and I've seen the ambulance there a few times in the past too so I'd say it's a chronic condition).
I think the next vehicle they need to learn about is the police car though, they can then be my lookouts. Is it just me or does anyone else always feel guilty when they see a police car behind them? I mean apart from bending the speed laws slightly I've never broken a law, but when I see a police car behind me I get twitchy.
