I wonder if this can be connected to a fatigue that I experience during clothes shopping. Whenever I enter some kind of a clothing shop I get super tired after 10-20 minutes of searching for something, while my girlfriend could do that for hours on end. (I hate shopping in general it just makes me tired :( )
I love both museums & shopping, but I also tire of both after about 20-30 minutes.
This is why I have memberships to my local museums, I'll pop in for 20-30 minutes at a time and be content, and not feel like I have to "make use of" an entire entry fee.
