Understandable, but does that make it right/acceptable to make that jump after only a few months?
It's a matter of degrees (pun intended). Many jurisdictions required a 1 or 2 year waiting period up until a decade ago. Now a brother can receive a signed petition and invitation the night he's raised. That's how the rules work now.
Right or wrong? Matter of opinion not of rules. Acceptable or not? Matter of opinion not rules.
I would prefer a Brother wait that 1 or 2 years that was once required but I am well aware that's my own preference. I recommend the number of years it takes to go through the line because that's what I did and it worked well for me but I am very aware that was just my own experience.
You're allowed. Masonry teaches following the rules and expressing our freedom within following the rules. I strongly value that freedom aspect. To me definitely acceptable for that reason no matter that it does not match my preferences.
