Here's something that happened to me in real life:
My sister is play basketball, and she finally scores and tells my father.
"So, you scored one of those 'touchdowns', did you?" my dad says sarcastically.
My sister replies, "NO! I wasn't playing baseball!"
If you don't like it and want math, then here is something.
.999...... = x Multiply by ten
9.999...... = 10x Subtract by x.
9 = 9x And divide by nine.
1 = x = which also equals 0.999.....
