LOL. The “invisible disability” argument was the first one on the thread. It happens every time.
Frankly, I think that young people are no longer trained to give up their bus seats to anyone. It’s simply not on their radar anymore. I am a senior auditor at a major university and I attend a university class twice per week. I take the bus to the university and back home. I am in my early 60’s and overweight, so no spring chicken and no fit elder. The bus home is usually packed with students and I have to board a standing room only bus. In the 30 or so rides back home not a single 17-22 year old offered me a seat. Not one. On one ride a seat opened up next to me and a young man blocked me and plopped down into it.
FTR, I don’t expect them to offer a seat and if they did I would probably decline. I’ve been “bus surfing” for probably as long as their parents have been alive and I can hang on just fine. Still, it’s an interesting observation that no one in 30 trips on a full bus over has ever offered a “granny” aged woman a seat. It’s just not baked in anymore to offer seats on busses.
