I've been dating my boyfriend for about a year, he's a PhD student. I know his research group was having a holiday party today. I actually haven't met anyone in his research group but have heard about them.
I happened to be doing a long bike ride today and in the last 2 miles, there was this narrow trail and a group of people walking and talking. I had to slow down a bit and also said "on your left!" and they started to get out of the way. One of them yelled my boyfriend's name (which is fairly unique) as he was walking towards the front of the group and he started/looked back and got out of the way, and then I suddenly realized it was him. I wanted to finish my bike ride though and felt awkward stopping so I just pushed the pace and kept going.
What would you have done? Felt weird to stop and chat...
