history: I didn't told a friend we were going to hike in the mountain because last time she was so slow and we had to wait for her I feel bat about it now. Yesterday we went hiking to the mountain and I didn't tell a friend we were going even when I knew she likes to come with us. Oh wow. Did your friend do something to upset you or something like that? Or were you just wanting some alone time?
current: No, it was just because last time she was very slow and we had to wait for her, but of course I now feel bad about it.
next: Well everyone has their pace. Maybe the next time you go you can invite her but take more time. It's fun, either way!
