Instant Family
In the early years of my marriage, before we had kids, my wife and I had 2 extra bedrooms. I had a co worker going thru a divorce and offered him a room temporarily. After a couple of weeks and things going pretty well, especially since he was working a lot, we offered he could stay longer-term and start paying rent and bills.
After about 2 months he gets a new girlfriend, not that big of a deal, she is around mostly on a weekend here or there. Fast forward another month or so and he has her bring her 4 kids to stay the entire weekend with us!
Keep in mind this was before we had kids so there is all the children that we don’t even know taking over our place and we felt like prisoners in our own bedroom. By the end of that weekend we requested that he find somewhere else to go. Story credit: Reddit / randoman00_00
