Things are getting crowded

When I moved into the condo I am living in now, I was living alone. It is a two bedroom condo, I thought perfect.  About 10 months later my eldest son broke up with his girlfriend and moved in with me.  Then my second son who went to school in St. Albert and all his friends there as well ended back home with me cause his dad moved to Redwater. Now my daughter who was living with her boyfriend in an apartment has been accepted in University for Nursing wants to save some money so moved back home with me......along with her two cats!!!.  So here I am, in a two bedroom with 4 people.  It's a really good thing that I have two reaaallly comfortable sofas.  The only thing is I have such little room left in the place with all the extra boxes, clothes etc. that I don't even have room to change my mind.  What can you do!!
