So I just got back from Gurdwara and I had an interesting experience I feel like I should share.
While sitting at langar, a singh came around to serve some food and seeing that I was gora and such, he promptly introduced himself, struck up a quick conversation, and shook my hand. To those of you who grew up in Gurdwara this may not seem like a big deal, but I can promise you this gesture means so much to an outsider. It honestly quit bothering me quite some time ago, but the insular nature of desis can be a bit jarring at first. I think this is even the case with other desis coming to gurdwara... people just tend to ignore them if they don't already know them.
I think this is just as valuable a form of sewa as serving langar, if not more so. So if you are serving langar and see a new face, brown or white, be a gentleman/lady and kindly introduce yourself. I promise it will make quite an impression.
*sorry mods, this should probably go in general*
