My last argument

The last argument I had was about allowing my cat to be outside the house with out a leash for a few minutes or not. It is not actually "my" cat, is "our" cat, my gf's and mine. My cat wnated to play outside for a few minutes but we were about to eat so I suggested to my gf that we should let him outside with a leash, a long one that allows him to play around a little while we were eating. My gf said that something could happen to him, or that could run away. She is used to having dogs and we all know that dogs run away pretty easy with out a leash; but im used to having cats! and I told her that they are fine, they never go too far away from the house if you let them  free, they usually just hang around the house, but free! So she agreed because of my experience on alloqing him to be outside, but if something that what she prevented happened, it was going to be my fault and the cat will ever get be out again by itselg. Of course I agreed, and after finishing eating we went outside and as I said, the cat was laying next to the walkway in the grass just enjoying the outdoors! so I won :)
