When somebody says "less fortunate" I think of kids that do not start tennis until early to mid teen years, not kids who were still privileged enough to somehow start early in their lives i.e 5 to 10 yr olds.
And I said I started summer before high school, in West Texas that is last four years of secondary schooling (9th through 12th), meaning I was 14 (By no means do I mean this in a bad/rude way, I am just correcting you since some places there are Jr Highs and others- like West Texas- only have Middle then High schools).
When someone says "less fortunate" I think of families that struggled to get by, and when I think of tennis and kids that start early, I think of those kids' families being off well enough to start their kids early. Of course that is not always the case, but it wouldn't surprise me if that is how the majority sees it.
Also, I meant to say "my parents were never involved", not sure if that makes a difference in how you read it.
If this is clear but we still don't see eye-to-eye, we can agree to disagree

no hard feelings from my end.
