All in a day's transportation...Case of the blind boy in a metro

There are certain advantages of taking the public transportation. I have discussed few cases of unique observations and experiences earlier. However today was something different. For the first time, I came across a blind chap with a nice dainty lady. Both were in jeans. The chap would have been in mid twenties and so also the lady.  
She was gossiping with the chap holding his hands together while waiting like me for the metro train to arrive. Initially there was a group of young people (probably friends) who were gossiping with them and then the group left them.
There was a degree of empathy in her eyes and that reflected in her face too. There was a smile and there was few milliseconds of an angst-look on the face in between. What struck me was the distinct bonding between them. As such, when one commutes in a metro it is not surprising to find pairs holding hands but this was the first time one of the partner was blind. There were like me, many pairs of eyes directed on this pair. Probably each of the onlookers had the same set of questions in their mind like what was the relationship, what they were discussing and what does future hold for them in conjunction with the first question. 
But before I could think of something, my station came and I had to leave. I left with one thought: happy that we have blind people being cared and also to discover that we have some patient angels.
