Why the guilt trip on the OP? The OP isn’t the one who blew cheese during the consecration.
He’s grown, what he did was immature, it was an accident.
I think OP is fine and does not need to be reassured of the situation in such a condescending manner or consoled with the aid of corny gifs (I think OP is over the age of 13, although I may be mistaken). If I’ve hurt someone’s feelings, they can tell me.
The OP removed himself from the scene in fear of becoming amused at another person laughing. That’s what the OP did about the situation, that you apparently find respectful. Or if you thought it was receiving the Eucharist afterwards that was disrespectful, then where are the three conditions for mortal sin?

Haven’t you ever realized that laughing, in and of itself, can be catching? Especially during an awkward moment when nobody knows what to do or think?
(I’m assuming you meant ‘disrespectful’ in the quote above), but yes, I did find his response
disrespectful. If I was present during the Lords Sacrifice on Calvary, and someone nearby “blew cheese” (as you so eloquently put it), I don’t think I would feel the need to draw myself away to hold in my laughter. I’m sorry, is that wrong of me to say? Because as Catholics, that’s the reality. I’m not gunna sugar coat it. (Also, no one mentioned mortal sin).
Sure it would be nice if we could shut off our human reactions and all be robots. Then we could “celebrate” the Mass perfectly, with total precision and zero measurable flaws. Think of it. Flawless perfection – not a sign of human soul in sight. All of our moves and gestures would be perfect within 20 milliseconds and 0.1 cm…
Cute, but spoken (directly) from our Lord:
Mathew 5:20: For I say to you that unless your righteousness surpasses that of the scribes and Pharisees, you will not enter the kingdom of heaven.
Matthew 5:48: Be perfect, therefore, as your heavenly Father is perfect
Now I’m no scholar, (and you can take those quotes as some arbitrary/haphazard response to his followers), but the Church seems to take it rather seriously (and I don’t think that’s such a bad idea).
If he told me to go to confession over it I would, but I’d bet three months of disability checks that he won’t. (Please bet me I need the money.)
If your priest(TemplarKnight1) is anything like the Pharisees (which would appear to be a
good thing according to scripture), then I’d take that bet!
A few weeks ago I actually discussed with my pastor about when I get terrible thoughts in my head during Mass. He said he has the same problem, that once in a while right during consecration something will pop into his head and he just pauses and mutters quietly and gently, “Come Holy Spirit,” and continues on. That allows him to keep his composure.
If you weren’t so hasty in your response you would have seen (or maybe you did) that after OP responded, I pretty much said the same thing, that:
“I find that many times my mind strays in such instances (oddly enough it’s always at the most important moments when I lose concentration), so it’s best to be conscious of what’s going on etc.”
In conclusion, OP either made a mistake or he didn’t. I think he knows full well what he is capable of, and his sincere and honest attitude towards the issue should
not (as I stressed previously) be downplayed. This is a
good thing, (and Confession is
never a bad thing, whether you have mortal sins or not), no cat meme/gif is gunna change that.
