After the groovy advice of my fellow JUsers, I decided to have a little chat with my roommate. I told her that it made me uncomfortable when people commented on my weight... even if they were complementing me. I didn't say anything about her doing, just people in general, but I'm sure she got the hint. Then, I mentioned that I didn't appreciate her commenting on my food choices. I managed to say it in a nice, non-accusatory way and she said she completely understood.
Then, as she was dressed to go for a run, I asked if she was heading out. "I don't know. I'm kinda tired." she said, "I may just stay in."
"Oh, come on. I'll go with you." I said. She stretched as I hunted for my shoe and then we headed out. She started running one way, and I started walking the opposite down the trail. Then, I don't know why, but I started running. I suddenly felt like it. So, I ran, and ran, and ran. (No Forest Gump jokes, please)
My roommate was headed my way and saw that I was running, turned around and ran with me. Then, when I couldn't run anymore, we walked to the other end of the trail. We decided that wasn't enough, and turned around to do it again. This time, we started running at the beginning of the trail, and didn't stop until we hit the end. She kept my pace even, and we were able to chat a bit while we ran. At the last ten feet or so, I thought my sides were going to explode, but I made it. It felt amazing. We walked the rest of the way back and to home.
She thanked me for getting her out and not letting her be lazy. Maybe, together, we can help each other out without trying those "guilt tactics" she was trying before.
I plan to go running again tonight.
