So true. This may come across as first world problems but here goes: once I forgot to take my wallet to the office; so no cash or cards (I had taken a cab and realized this once I reached office). I had to borrow some money from my co-worker (which I was quite uncomfortable about since I have a bit of an allergy about borrowing money). That day, I repeatedly calculated how much I had left to ensure that I had enough for lunch, dinner (which I used to do near office) and transportation. Not even close to hardships of someone dealing with real financial challenges but it was like a sneak peak that I stayed with me.
