One set of random guest was his father and brother. Much like he, they were nice people, nice people that lived with us for three days.
Day two of their stay Father Roommate decided to whip up a dish in the kitchen, sadly I was on my way out, therefore missing the delicious dish, however I did have time to take part in some light conversation before leaving. So we did.
We chatted about where I was going, what I do, where I'm from....then about what he was cooking, what he does and where he's from. It was around that moment that the Roommate entered the kitchen. He chimed in regarding the 'where's he's from' question and offered a quick tale of growing up there. Then silence hit. In retrospect I should have said a polite 'nice talking to you enjoy your dinner' and moved on, however for some unknown reason I felt the need to indulge in another comment.
"Wow, ya know, you two really look so much alike! Like it's almost crazy how much you both look alike!!!"
Blank stares in return.
Cue Roommate "....Uh...I'm adopted"
"What?! No you're not, look at you two!"
Cue Roommate and Father Roommate "Uh yes"
"Really?...Oh...huh...(awkward smile)....how about that...well I got to get going..."
Looking back, I do (vaguely) remember Roommate telling me he was adopted upon my moving in. Would have been pretty awesome to have remembered that.
