<p>OP: You should learn to accept people as they are instead of complaining behind their backs.</p>
<p>Though, from the sounds of it, it seems like your roommates are just uncomfortable to the college environment and thus don’t feel like doing anything too adventurous. Based on your description of them, if I were you, I’d continue to invite them out to dinner and mention what you just said to them (save for “lame”). See their viewpoint, and if it makes no sense, try to work thru a common understanding with them.</p>
<p>At least one of you will learn something in the process, and this is one of the several things about life that you should learn in college.</p>
