Perhaps you should ask your sons, why they don't they invite friends to your house to spend the night?
My children are now age 29 and 27 and married with children. From early elementary school and on through high school my kids had friends over every Friday night. Some Saturdays and an (rare) occasional week night.
Frankly, I loved it! I realized our kids were no longer "ours" they were becoming citizens of the world and I wanted to participate in their lives.
Our kids and friends were not allowed to "hole" up in their bedrooms. We ate together at the Dining Room table. The only TV was in the family room. (My husband was more liberal when it came to allowing certain movies and games.) Although, I always welcomed visiting kids and mine to explain (politely) and challenge my objections to a video or game. Lively debates ensued! Sometimes they were right! My husband and I almost always watched movies with all the kids, (yes, even in High School.) I never was evacuated to my room, and yet they kept coming back every week.
It's up to you to decide, do you want to share your house and personal time with your kids and their friends? If yes, I suggest you cook from scratch to save $$ on feeding the hordes.
I wish you the best!
