And...
My mum was coming to stay the week before DS was due. We'd faffed about trying to decide which airport she should fly into. There are two, Vancouver Int'l which is just over an hour's drive from our house, and Abbotsford, which is 25 mins away in the opposite direction. The flight from Toronto into Vancouver was much cheaper, but I'd been told not to drive anywhere outside of our local area by myself at this point because of risk of precipitous labour. (Considering that I ended up labouring for 36 hours, this now makes me laugh in a slightly hollow manner...) So I could have sworn mum decided to fly into Abbotsford.
Cue me, on the day of her arrival, driving to Abbotsford airport, standing in the (completely deserted) arrivals hall, stupidly looking at my mobile after receiving a text from mum: "I'm here, waiting for you at the baggage claim". Since I was staring at the baggage claim, where there was not a single solitary person, I texted back, "which baggage claim?"
Eventually we got to the "which airport" part... apparently I had completely forgot the conversation we'd had about her flying into Vancouver because it was cheaper and that I would ask my MIL to drive with me to pick mum up.
She ended up taking a taxi to my house as it was 4 pm, desperate rush hour time, and it's almost two hours from Abbotsford airport to Vancouver Int'l.
So when mum booked her and stepdad's flights for Christmas, she emailed me the dates with "arriving at Abbotsford" in bold...
