I've 5 teens here. It's another 'phase', we experience. This one lasts a bit longer than the others.
One minute they can't be without you, they're your shadow, you can't even go the loo or shower in peace without a million questions. Then suddenly they are in their rooms, off with mates etc. I do have a full house but it feels empty as they're doing their own thing.
My 5 are totally different, planning anything is impossible. The only thing where we all come together is holidays but that's not happened this year or last year.
I usually just go with them on what they want, I tried the family meals, the men would shovel their food down in 20 seconds, the women chat and half the time argue over who robbed whose top etc. We had all of meals together when they were younger, did the day trips together, sat watching movies together, went for walks together but that changes naturally as they are becoming more independent. The one thing I do ensure is the minute one wants to chat, I mute the TV or stop what I'm doing and listen, I think from always doing that they can talk to me about anything.
I am looking forward to restaurants re opening as we also enjoy doing that as a family. All you can do is be there for them, to not force things on them as their likes are changing. They will enter a new phase after this where they'll not be so embarrassed by us.
I was even a little surprised the other evening when I was going for a walk and I shouted up to them if anyone wanted to come along, I was surprised to see my 19year old ds come down ready and along he came, he never does this, we had a really good chat and it felt really nice.
