|Can I sit down now, please?|
There is an empty seat next to you and a lady comes up and gestures to her lanky teenage son to take the seat, which he does as if it is his right. (His mother, after all, has been ceding him her seat since he could stand.) You stand and gesture to the lady that she should take your seat so she can sit next to her son.
The people sitting across the aisle notice this and scrunch together so you can sit down with them.
