Sitting by others doesn't necessarily mean playing with them, even if the elderly people are grandparents and the baby their grandchild - neither of which is necessarily the case.


Context: Two elderly people are sitting on a couch by a younger woman in a pink shirt who is holding a baby.
Hypothesis: Grandparents smile as they play with their new grandchild.

Given this context, is the hypothesis true (Yes/No/I don't know)?
