Good post.
I remember my timeline pretty well because I had an airline ticket purchased and needed to make a decision.
Jan 30th---At the end of January I was aware of the virus, thanks to Amonet and this thread that was started. And it did spur me on to buy some extra medications, TP , water jugs and canned food.
Feb 2nd---In early February, my older brother called to remind me that he was going to be out of state, when my Mom was celebrating her 90th birthday. On our Christmas visit I had promised to fly up for that party.
I went ahead and booked a 2 week flight, from LAX to Reno, from march 7th to march 21st.
March 2nd---...after reading this forum, I began to feel a bit nervous about the flight and going to LAX, etc. My kids didn't want me to fly, but as I told them, my Mom was having a milestone birthday, and I didn't want her to be all alone.
I even had a private conversation with Margarita about this stupid decision, and she set me straight about the possible risks...
I flew on the 7th, and wore a mask and gloves. I didn't see anyone else wearing any PPE, until I passed Japan Airlines, and saw an entire flight of departing passengers, ALL wearing masks.
Mar 7th--Even the flight attendant asked me if I was ill....

....I said NO, just preventative measure, but she seemed to think I was a nut case for doing so....
What a difference a week makes.
My Mom lives in her own 2 bedroom apt, but it is part of a senior community complex. So there are a lot of communal activities and restaurants etc, hairdressers, exercise classes, for them to take part in.
March 11th--While I was visiting, things imploded. The NBA cancelled their season, and people were suddenly aware of the coming crisis.
I went to the local grocery store and bought my Mom a month worth of supplies for her kitchen. She had voiced a lot of concern about not being able to get out, as the Community shuttle bus had been cancelled.
Mar 12th---In fact, by March 12th, her Senior Complex asked ALL GUESTS to leave as soon as possible. They were no longer allowing the residents to have visitors, or to use any of the communal areas.
So I flew home a week early. Thank goodness for trip insurance.
Mar 13th---what a difference....LAX was full of people wearing masks and gloves. Not everyone, but way more than just the previous week, where I was the only one. lol
I have been pretty much on lock down since March 13th. So far so good.
