Maybe it's a CBR thing?

I've left my sunglasses on the security belt before. I loved them and couldn't see where to buy them again, so decided I'd fly from NZ back to CBR to get them and do it on the cheap. Thought I'd take the Qantas red eye from Melbourne back to Auckland because I thought NO ONE would be flying that - what a terrible flight! I'll probably get a row to myself! Next minute.... the flight was chocka and I was thinking "what's going on? It's like everyone's flying home for Xmas or something - that's how full it is!" It. Was. The. Worst! After much grumbling and thinking I realised that Sydney has it's curfew, Brisbane doesn't have late flights and Melbourne didn't seem to have that issue and Perth... well Melbourne is enroute so realised basically after a certain hour everyone in OZ gets funnelled through Melbourne if you want to get to NZ with a very late departure! I swore I'd never do it again but later.... got notice of a family emergency and that was my only option again to get out of Oz. I think I put in for an upgrade whilst transiting BNE as I just thought... I can't face that flight again without some comfort. Upgrade came through. Unfortunately that process meant my bags were dropped from my flight but I was warned that was a risk and I was like "I'll take it!" Landed in Auckland to a sign with my name on it and I knew immediately my bags didn't make it but Qantas got my bags to me in a few days as I had to be in central NZ. Thank goodness for cheapie shops like the warehouse and kmart or target etc to get me through. I think my travel insurance policy said something about only claiming if I was out of pocket by $500. Didn't want the hassle so cheapie stuff it is. I had more important things to attend than deal with travel insurance.
I know I've left my toiletries bag at the hotel in CBR as well as I woke to a text from VA my flight had been cancelled and I'd been rebooked on an earlier flight. The toiletries bag was on the hook on the door in the bathroom so I never saw it in my hurried packing. Don't think I flew back for that one. Must have got it sent to me or a friend to pick up from later.
