I live in Edmonton, Alberta. The show is in Montreal, Quebec. The price for a round trip ticket would be ~$500. I may be able to get a hotel and flight as a package for around ~$600 for one night. It's a four and a half hour flight if it's direct with no connections.
Yeah... I priced it out.

I even spoke to mum about it. Unfortunately, today the nurse came in because she accidentally took two of her painkillers and she's now on fluids under her skin to help flush out her system and prevent toxicity. It really freaked her out and she was pretty upset. I did take the step of speaking to the nurse about accessing additional services (hospice care, volunteers to come in, etc.) and we'll be talking to someone tomorrow. But all that aside, I really couldn't leave without causing her emotional suffering. And that's a price I just can't pay.
But THANK YOU to everyone for caring. It's such a silly thing, looking at paintings, but it really would have been amazing. I have already contacted someone I know in Montreal about picking me up the show catalog. It may not be in person, but at least I'll be able to see the studies and sketches which aren't really published anywhere else.
If something changes and I can in any way get my little butt out there I'll be sure to update.
