Please be extremely careful with slippers on rainy days

While I was on my way to pick up my son for lunch today, he suddenly asked me if I should call 119 for that person.
When I looked, I saw a young person bleeding from their head and collapsed, shivering uncontrollably.
I called 119 immediately, and when I asked what happened, they said they had slipped and fallen on the curb next to the road.
The 119 emergency responders arrived and took them away; I truly hope they are okay.
The curbs and edges of sidewalks next to the road are extremely slippery when it rains.
In particular, if you are wearing slippers or sneakers with flat soles, slipping can lead to serious injury.
Please be careful and try to avoid stepping on the far edges of sidewalks on rainy or snowy days.
