I have a couple that apply here. There are a few guns that I just very much love to shoot, and when I find the time to go to the range, these are the ones that I always take.
I'll get around to shooting the newbies one of these days.
There are a few that belonged to my dad (who passed away last year) that I've never shot in my life, and for sentimental reasons I've never been able to bring myself to shoot these. One of these days though, I'll run some rounds through em.
