Would there be any reason not to tell anyone you got a grant for a home you just purchased?

I’m purchasing a new home, and I qualified for a couple different grants, I actually don’t have to pay anything on closing day… i’ll have a mortgage, obviously, but the grants helped out so much that my closing day cost are zero dollars… (they’re actually paying *me* like $70)

Is it wise not to say anything about this to anyone, including friends and family? Because they might be envious if they had to pay a lot of money towards their closing day, or they might not agree with the grant system because it basically means they, as a taxpayer, paid for that to happen?

Or am I overthinking this and is this not a big deal at all?
