Have you ever got sick of forums in general, like you have been on them that much, ran them that much that you ended up just hating the site of them now and then? Ive been like this quite a few times where even just looking at a forum has given me a headache, so I take a break and when I get back to them it goes away. Ever been the same? even about any other website type too.
That's how a lot of people are about a lot of things. But I'm the same way. Often, I'll take anywhere from a month to 6-month breaks from forums, websites, and even gaming. Especially during FIRST robotics season. I'll have my online time as a whole cut down to 4-6 hours a week, generally. And now that I'm starting a new team, it may dwindle down to near nothing. But I do get sick of theme every once-in-a-while. Can't stay away for long, though.
I know you were upset last night, but I'm sure there would've been plenty of people here willing to give you actual money for that license... That said, I hope you change your mind and that your friend is willing to give your license back.
