Depending on the culture in your country, a sympathy card could be a good thing to give. You might find a card that says something compassionate, then add a personal note expressing your condolences and offering to be a listening ear at work or outside work, or if they’re looking for a distraction you can be that as well. Something along those lines might be appreciated. It of course depends largely about the kind of relationship you already had with the coworker, and what kind of time you’re willing to offer her outside of work (if her mother had been living with her, for example, she might need someone she can call in the evening to talk when facing that loss).
We did, for both games, although we didn’t play Operation much. It kind of lost its novelty fast, especially with the buzzer the TV commercials conveniently left out.
We played a lot of Mouse Trap, though. Everyone complaining about the trap not working half the time seems to have missed that that was the point. You might land in the trap zone and have one of your siblings get the chance to trap, but it wasn’t a guarantee that you’d be trapped. If it was going to work every time what was the need to even do all the building? At that point it’s just a game with an instant lose square. If the trap worked or failed you needed to reset it for the next attempt, and as part of that reset you could adjust or fix any parts that had failed. Or maybe try to subtly sabotage it again if you’re worried you might be next…
