One easy way to estimate someone’s loyalty is to see if they have friends from different stages of their lives. How many old friendships have they carried with them over the years? Did they ditch their college bestie when they got depressed, or do they still meet up for monthly movie matinees? Do people from their past seem to rely on them for companionship and support? Of course, there are exceptions to this rule, since some people have moved around a lot or lived in places where they didn’t fit in. But in general, old friendships indicate loyalty.
