I have a brother and I'd say we were reasonably close. We talk or text once every two weeks or so. Most of it is me texting him and him suddenly remembering he has a sister (ha!) and responding. When we do text, we always exchange 'love yous' etc and occasionally he'll randomly message me to say he thinks I'm great etc. We live about 400 miles apart so not that easy to see each other regularly.
Just wondering if others have brothers and what your relationship is like?
