When we all finally left the nest, my mom bought herself a two bedroom patio home. Well as justamom states statics are that at least one of us would return. At one point or another all four of us have stayed with mom.
I moved in when I left my ex (which is the best thing I ever did) and I brought my little one with me. Then a few months later my sister broke up with her boyfriend and she moved home. A little bit after that my youngest sister got engaged, her future hubby was deployed and she didn't want to get a new lease because she would be moving, so she moved home for a few months while we prepared for the wedding!
What I learned is that each one of us had a different relationship with mom, and a different way of dealing with being at home. Mom & I fight the most. The youngest is like best friends with mom. The middle wants mom to take care of her. It is really funny.
Needless to say, my daughter loved those months having that small house crowded with girls. Always someone to play with, even though the youngest was 23. And last year when no one was home, I think my mom might have missed us. When my last lease was up she talked me into moving home again.
