My girlfriend and I have an awesome party. It's made up of friends that we love. Interacting with them and hanging out with them is always really great, but there's a slight problem that's fluctuated between getting worse and getting better.

DnD is a game, we want everyone to enjoy it. We both run serious campaigns, but we want there to be room for goofs and joking around. We love it when they joke and we laugh with them most of the time, but it's started to be an issue where they talk over us when we're trying to explain or interrupt us when we're talking.

We wanna fix it but we don't know how we could bring it up in a way that won't make anyone feel bad. Any advice? 

If they are your friends, just talk to them. They should understand.

On one hand, if they are having fun - great! You can totally slow down the game and enjoy it.

On the other hand, if they are talking over you and not paying attention then they may have become too complacent and you need to raise the stakes to get  them scared and paying attention again. 

And on the third hand (:p), if what is actually going on is that they are disrespecting your work and not engaging with the world then... That's a whole other problem. 

Ultimately, you need to chat to your players and let them know that the way the game is going currently is not fun for you. The goal is to find a style that everyone enjoys, but this is not always possible and not every group should keep playing. 

@Wysperra That's true, thank you. :3

@Garr_Feyld I think you're right about that. I did raise the stakes a bit last session, ended it on a scream in the middle of the night, but that session had gone really really well. It's the oneshot that's being trouble. I'm getting it wrangled but I worry at times that I'm being boring.

@Lyxen That actually makes me feel a lot better about some of my worry. I think the consensus is that we should just casually remind them that we'd like to finish our descriptions, but I wanted to state that I really appreciate the perspective you just gave me. I thought it had been a discredit before but I feel a lot better about it now. Thank you :>

If it is bothering you then just talk to them about it. It's no big deal to have a chat with friends to make things fun for you as well as them. Another option is to change your perspective slightly. What I do if my players start talking over me is I let them. I just stop talking or trying to explain things and let them finish. The Adventure isn't going anywhere, monsters and NPC's aren't going anywhere so there is no rush. I ask if they are ready when they finish and we move on. So long as they are having fun Im content to let them talk and role-play and hash things out. You need to use your own judgement for this though. There is a difference between talking that enhances the fun of the game for everyone and talking that takes away from the fun of the game.
