Last session (I GM Traveller, a hard science fiction rpg) I realized my lack of skills when I found myself willing to spend some minutes in playing a scene involved a 3 years old child causing trouble while in the spaceship and getting measles and passing it to all the spaceship crew.
It went this way:
during the takeoff
Me: "The girl feels sick, she vomits your bridge."
Captain: "Ok, we get to clean it."
Result: no fun
later, while in jumpspace for a week
Medic: "Since she felt sick while flying I check her health status."
Me: "You find she has measles." "Everyone, roll to see if you get it too."
roll roll everyone but one is infected.
Me: "... Everyone feels weary during the trip..."
Result: no fun
after a week, exiting jumpspace
urgent stuff with dice rolls involved is going to happen Me: "After a week you are no longer ill but cince you are still weary you get -1 to rolls"
And I really don't know how to do this better.
Related to this but not sure how much is a scene involved the crew joining a Imperial Navy Officers (plus an Admiral) dinner.
It went something like
"You see it's a less formal dinner than you thought, the food's good, you start chatting and relaxing thanks to the wine."
"You, Chris (ex diplomat), meet an officer who serviced with your father back in the days, he remembers him fondly but did not sees him since years ago" Player: "Ah, good."
"You, Lucien (the medic), get to talk with the First Medical Officer, you star talking about medical topics and he tells you he'll like to show you the ship advanced infirmary"
"You, Vincent (the ship Captain and ex showman/artist) make everyone laugh and friendly with your charm."
It went more or less like this, with me incapable of make happen something interesting and causing me to skip this scene... while I would have liked to add some interesting moments.
And I realize that this kind of problem could happen many more times if I don't get better at this since this is a high-roleplayed campaign.
Be aware that I know I could give them hooks or useful information during this type of scenes, but right now I'm more interested on the mundane aspects of the scene.
Now I must point out two things: the first is that I feel partly is cause for my lack of experience of being a player (I've always been only a GM and I'm still quite newbie) so I don't really know how a mundane scene could be interesting for players.
The second is that I've very little to no time to prepare my sessions, and because of this I'd prefer answers focused in improvisation.
Question: how can I improve this kind of scenes making them playing worthy and interesting?
