Once I picked up a hitchhiker and gave him some weed.

Not really big or anything, but almost 20 years ago it was my first time visiting Vegas from across the world to attend a conference. I had a very limited travel budget and was carrying three $100 bills as my allowance provided by my employer. Took a taxi from the airport to the hotel and it didn't cross my mind that most taxis won't really have change for $100 for a $12 ride. The driver was kind enough to just let me go without paying, probably because she could tell I was a tourist and was panicking because I had nothing else to pay with.

Old HR lady, rejected me as soon as I entered for the interview. She scholded me and spend about 2 hours teaching me how to act at an interview. On the same after noon I had 2 other job interviews, I got both jobs and I got to choose my "dream" job that ended up sucking and I should have taken the other with bigger pay. (But hey that HR lady really helped me a lot even if she did not have to I was rejected about 15-20 times at interviews before I met her).

Once saw some people giving a big box of food, dog food, and supplies to a man with dogs that looked homeless and he laughed and turned it down because he wasn't homeless, he was just on a camping trip, had taken a fall, and was currently waiting for someone in the store to get a first aid kit to clean some cuts he got.

When my neighbors said my family could sleep on their couches. I slept on the couch of one neighbor. My brother went to a different neighbor and my mom to a third place. It was either that or the car in a parking lot. This between my junior and senior year in high school
