When Is A Dinner A Date?

Sometimes existence is more limited and sometimes it is really blurry. I am not sure which of the two are better, but right now I am leaning to ward the former.

I went to dinner last night with a new friend, one who has occupied much of this blog since its inception. Now I am not sure if last night would be considered a date, or if it was just two friends meeting up for dinner. I can explain how we ended up there and maybe you can help me figure out the appropriate title for the dinner. As you should know by now, we met randomly after not meeting. This was followed by another meeting at a crowded bar with a bunch of her friends. After this I casually invited her to meet up with my group on Saturday night even though I knew she probably wasnt going out. Since she didnt go out on Saturday, she suggested that we meet up and do something that didnt involve alcohol (as she was intoxicated the two previous meetings). And this is how we arrived at dinner after a little rescheduling. So it was not as if I just straight up asked her to go dinner and she did not originally ask. So was this a date or just two people meeting up for dinner?

I am fine with either answer. The dinner doesnt really give any clues because it was a lot like a first date and it was a lot like hanging out with a new friend who you barely know. So back to existence... I am hoping to move away from the blurry and head back to the limited.
