Conversation with my grandmother:

Grandma: "Everything ok with you?"
Me: "I've very good. School, work, ManWriter is coming in town for a couple of weeks."
Grandma: "You two have been dating a while. Things must be going great."
Me: "I wouldn't stay if they weren't."
Grandma: "He stays with you when he comes into town, right?"
Me: "Yes..."
Grandma: "Are you two engaging in premarital sex?"
Me: ".................................................quite possibly."
Grandma: "Are you enjoying it?"
Me: "Very much so, yes."
Grandma: "Make sure it stays that way. It's 90% of the relationship."

My grandmother is awesome.
