I have had a fair amount, including the welcome I got to my current FC and many moments with them!

...but the one that immediately came to mind was when Tamago was sitting on the ground in the Gold Saucer waiting for GATEs, and a cat boy came up and asked if I was okay and gave me hot chocolate and cookies. We ended up in the same Leap of Faith and he very patiently waited for me to painstakingly finish so that he could cheer me at the end.
