Do not Worry.
I have an only daughter & it was just the two of us for many years until she went away to college & had many roommates over those years. She always loved to go on trips and travel, but always wanted to come home early. Once she moved out on her own.....she said she never wanted roommates again.
Of course, her furbaby and cat are lots of company for her.
btw: where are those adorable babies of yours? I miss the videos, they were the Cutest!
