I dunno, Nuke... I for one could TOTALLY see you becoming BradPittANoochie. In fact, I think you grow to be more and more one with him with every post...
If someone invited me to do something I'm not interested in, yes, I might agree to it just to spend time with the person--some things aren't that enjoyable to me on their own, but they're not so bad with another person (doing dishes, for example.)
The other angle is that I may not know anything about what the person is asking me to go see or experience, so my saying yes isn't being insincere, it's trying something new because I can't be sure if I like it or not if I haven't at least tried... I mean, if Nuke asked me to go watch some kind of... I dunno? Live welding presentation on monster cars? I'd agree because I've never seen live welding on a monster car before!! So, I wouldn't know what I thought of it unless I tried going...
I kind of see some things as being like food--it can become an acquired taste... and sometimes you need to learn what adjustments have to be made to make the experience more enjoyable. For example, I'm not a camping person--I have problems with sunburn, windburn, extreme heat, insect bites, and the thought of using a tree as a bathroom. However, I HAVE spent weekends at campgrounds in a tent or camper--in other words, there was a bathroom and shower available, and the weather wasn't so extreme (I actually loved it when it rained) and had a perfectly enjoyable time, for the most part (of course, throw in visiting Cedar Point and you understand my motivation...)
You might not like baked potatoes at first... but add the sour cream, bacon bits, chives... and BAM!!! Suddenly it's not so bad.

you just need the right condiments!!
