I'm sure it's been some time since you've been in high school, since you're a grandad, but I need you to understand something. It's spelled high, not hi. You took the time and effort to tell a kid to shut his mouth, and you saved an extra one second to not include the gh in high. If you want to set a good example like you're asking Pups4ever to do, you should do the same yourself, otherwise it does not mean as much.
