I'm an Engineer and I work full-time (8 to 5) in the city and occasionally I go offshore for a few weeks. I go for bike rides in the morning a few times a week, and during the week after work I normally go to the gym and then chill at home.
I'm pretty tidy and easy to live with, always up for a chat/drink but I'm also respectful of people's space.
I do come with a Cat, Loki, who is a young Ragdoll. She's an indoor only cat but she's pretty chilled and friendly.
