<p>My D is 23 and my S is 19. He has a friend who is 21. I think the friend has a crush on D, and I also think he’s a sweetheart. I also know this is none of my business, but D seems to light up when the friend is around. I was just wondering if any of you have seen romance bloom with a friend of a sib, and if it worked out.</p>
<p>My brother married my best friend from college. At first I worried that I’d lose a friend if they ever split up - they both are a bit quirky and prickly - and my brother traveled a lot when he started his own business which my sil found very trying when she had a house full of toddlers. They’ve been married over 25 years now, so I think what I liked about her is also what my brother liked about her.</p>
<p>My son married the sister of my daughter’s best friend. When the marriage ended, so did the friendship</p>
