Just when I thought I'd finally settled on a type, I am starting to doubt that I'm Si-valuing, let alone being an INFj.

I'm going to recall something that happened last night, when I was with my friends, and I want to know whether the incident is in anyway relevant to Si (because I realise that I may be falling into thinking about these things in a stereotypical/superficial way).

Three of my friends and I try to meet up every week or so for band practice. Apart from me, there are two guys (ISFp and INTj) and one girl (not sure of her type, I thought ENFp, but ISFp or even ENTp is possible I guess. Si valuing I think - I'll call her Friend A)

For the past few weeks, we haven't had the whole band there because everyone seems to be busy with their uni work. Anyway, this week, finally, we managed to get everyone to turn up. We agreed to have it from 6:30 to 9:30 (I would have preferred longer, since I wanted to make the most of everyone being there, but we had restrictions). The ISFp had told us that he wouldn't be able to cook this time, so Friend A, who was craving seafood apparently, decided to pick up dinner for all of us beforehand. I wouldn't have minded making sandwiches (because its quick and easy), but the INTj would have made a huge fuss about how sandwhiches aren't dinner food, and how he can't function without a good dinner.

This is where I start feeling very different to the rest of them. Friend A arrives 40 minutes late, meaning our already too-short practice is cut down to under 3 hours. She brings with her a huge pile of seafood (way too much, considering the lack of time, and also pretty expensive, considering they all say they don't have enough money to buy some of the equipment we need), and the ISFp and INTj start to salivate and gush over it. "Ohhhhh thanks so much for buying all this, it looks delicious, you really didn't have to". This is despite the ISFp previously feeling sympathetic about my annoyance at the her being late. I secretly resent his lack of consistency.

We sit down to eat dinner and they all start discussing the food and how good it is. It seems to me as if the whole point of meeting tonight was to eat dinner, not to work on our music, which is annoying. I encourage them to eat quickly so we can start doing something productive. They don't really listen to me/take me seriously, because I'm always saying things like that. The INTj finishes his dinner quickly enough (by his standards), but the other two are intent on devouring the whole pile of food. They've had enough but the food is apparently so good that they want to keep eating (like I said, there was too much).

After I finish eating I go into our practice room and start working on stuff by myself. It takes about 10 minutes for the others to finish eating. By now we have under 2 hours to work on stuff, which is really annoying because it's uncertain when we'll next be able to meet with the whole group present. The ISFp says he feels really tired after eating dinner and lounges around looking really unmotivated. Friend A starts to complain about feeling bloated and nauseous after eating too much food. I tell them they all lack foresight, and they laugh and agree.

So thats the end of the story. This wasn't a one off thing, because everytime we meet up, the focus seems to be on sitting around, joking and eating food, rather than actually working on stuff.

I appreciate anyone having read through it, if it didn't bore you to death. Are there any socionics related insights (particularly related to Si) that could be gleaned from this, or was I just being a bitch?
