No problem!

I've never lived in Kingston, but I think that both RMC and Queens are around there.

sit at a desk all summer doing nothing.

Eventually it might get better? I dunno. I don't know much about military life.

If you take the initiative and do extra things, you can maybe gain extra summer-employee powers? Dunno.

Here's a vaguely-related comment by a computer guy who read computer-programming manuals during idle time at his summer job, and gained a lot because of doing so.

sorry if that sounds rude

Not rude.

I try not to mention it to my friends

You can just tell them that, thankfully, you did well.

Clubs

You guys can start a nerdy club, to help future nerdy students, if you wish :) This might be a good experience, but is optional.

I kept it to myself (and reddit)

Likely not an ideal plan; but luckily you survived and are doing well now, which is the main thing.

Thank you so much for caring. It means an incredible amount.

Thank you for your kind words :)
