I never thought it was odd, but as my DS was growing up and his friends were ALWAYS at my house and I was feeding them more often than not, I learned that most of the boys didn't have a from scratch meal almost every night, and moreover, ate the same meals night after night. DS's BFF said his mom made pasta with jarred sauce most nights of the week. I'd go out of my mind if I didn't come up with different things to make and we had the same things over and over each week or night, for that matter. And, before anyone asks, we DO eat leftovers.
I also guess it was weird that I fed his friends all the time. When DS was at their houses and it came to dinner, he was sent to the living room while his friend and his family ate dinner. I couldn't imagine eating and not offering some to our guests, even if they were my DS's guests.
