<human>: I randomly bumped into a guy I knew from school at the mall last week. I didn't know him that well but we played games online on the Xbox a couple of times about 2/3 years ago. We hadn't spoke or seen each other since.

Anyway, we made eye contact in the mall and immediately recognised each other and smiled. He probably would've carried on walking but I went up to him and we talked for about 2 minutes before I initiated goodbye. He was chatty enough but wouldn't look me in the face. He keep looking sideways. He also apologised for looking a mess but I don't think he looked a mess at all.

Very late on Christmas eve, I was on Facebook and not long after midnight a Facebook message popped up from him saying 'Merry Christmas missy'. We chatted for 10 minutes or so about things and then I went to bed.

What do you think this means? Could he be interested?

Give me a shortened version of the text
