We share a 2 bedroom flat. So my housemate is going on holidays for 2 weeks. She wants to let her friend who is a couple (they are also travelling) to stay in her room for that duration. I  like being alone and not socialising when I’m home. I don’t really know them and I feel extremely uncomfortable living with strangers (albeit they are her friends).  Should I just be a nice guy and feel weird in my own home during that time or am I the asshole for even feeling this way. Thanks
