person A: So yesterday I found out my roommate has been dating someone for 3 months. I can't believe he didn't tell me.
person B: Wow_comma_ that's a good amount of time. Is he usually so secretive?
person A: He is usually a very private person. He hasn't dated anyone in the over 3 years i've lived here_comma_ and he's only ever had one friend over.
person B: Ah_comma_ maybe he just wanted to make sure it was going to work before he told anyone.
