I have to say I missed 5 out of the15, but here's why:
1]Over the years, I've gotten most of my books either through book clubs, or through internet thrift book stores, so reading a chapter while in a brick and mortar book store is something I haven't done--yet!
2]If only the question had said "bus station" instead of "airport", I would have been able to include it in my tally. I've been in lots of airports over the decades, but I only remember buying books before boarding buses!
6] I didn't include this one since it's been quite awhile since I've had the time and opportunity to actually read that many hours during a week,
8] I follow a few authors on Amazon.com, but not on social media--I was kicked off facebook awhile back, due to my saying that I supported a certain treatment for the CV-9 virus of which they didn't approve, even though now it's come out that the treatment is safe and effective.
15] I wish I did own a piece of clothing that proclaimed my love of reading!
