"Don't cross your legs."

When taking the subway, passengers' personal space is often invaded by people sitting with their legs crossed.

This issue has sparked a variety of reactions online.

Recently, a photo was posted on social media with such complaints.

It is a picture showing a passenger sitting in the adjacent subway seat with their legs crossed.

Netizens expressed empathy and a range of reactions toward such discourteous behavior in public transportation.

Some pointed out, "What did the person sitting next to them do to deserve this?"

Others complained that they constantly have to worry about shoe marks getting on their pants because of people crossing their legs.

Behaviors that cause inconvenience to other passengers by spreading legs too wide or crossing them on public transit have been persistent issues for a very long time.

It seems that as much as one is comfortable, others are bound to be uncomfortable.

In cramped spaces like the subway, how about paying a little more attention to how we position our legs?
