Personal space is important to Ren, so his initial reaction to being bumped into is to shoot a glare in the direction of the perpetrator. The apology comes unprompted though, and Ren is reminded that making a scene in public like this is a poor choice. He doesn't want to be kicked out before he can get some of this food.

He looks the stranger over, a strong looking man. Older. Probably someone's father. Ren barely catches himself from curling his lip in distaste. He doesn't exactly have the best relationship with his own.

"It's fine," he says shortly. He turns back to the table he had been perusing while trying to ignore the incessant thoughts from the children that were hanging around hoping for a free treat.
