It's no so much "I don't give a shit.", but rather that you are making a big deal out of something that totally isn't. (And even if it were, how you act has a very large effect on how others around you react.)
If you act all weird about it, you may get strange looks because you are acting weird, but that's about it.
This is true for a lot of things, so use this as practice so you can get rid of awkward moments. The problem is that it's a mental block, so it takes some time to get over, but eventually you'll look back and think that it was no sweat.
Go for it..!
