I'm thinking of gifting my great grandfather's congressional medal of honor to a museum vs. giving it to my cousin
Do you think your cousin would support your decision to do this?
My cousin does not care what I do with it
If your cousin does not mind giving it away, then you should give it to the museum. Your great grandfather's medal will be on display for everyone to see, and it would be a nice way to remember him.
Plus my cousin is kind of a slut, so I don't know why I would give it to her in the first place.
You should be thankful your cousin is cooperative and supportive of you choice rather than refer to her using such ugly names. How do you think she would feel if she knew you thought of her this way? You should be more respectful when thinking and speaking of others.
