I didn't know it is a requirement to get married to become a priest - I thought that if you choose to be married then you must be so before you enter the priesthood. If not, then you have a different direction of your priestly duties. I do think it came across pretty recently that it is a good idea to wait for the priest elect to mature to MAKE sure they don't take their vows and then abandon their post TO get married.
I laugh too, when I'm surprised.
And sometimes it comes off as a arrogant - but it's not intended that way . . .it's just usually something soooooo far from my thinking that it rattles me a bit before I can even comprehend it. . .and laughter is, I guess my first expression for lack of words to say. I'm usually quite speechless.
If your confession was pretty bad in you're view, then maybe you were humble enough to speak it and renounce it. Perhaps this is what your confessor was hearing. . . a true confession has to come from a humble heart and broken heart. I don't know - I don't know his or your heart, only God does.
Try not to judge his words for small talk. . . some things are incredibly hard to put in front of someone . . without getting 'laughed at'. . .he may have been just as nervous presenting the idea to you as you were when you received the idea.
I'm of the idea that God calls. . .and we make choices to follow or not. In order to keep from being puffed up in this idea, get your affairs in order and treat your life as if this is the last day you have on earth - and God will do the rest. He's the one that makes His Word come to fruit. You don't. Your priest doesn't. Ask your priest to pray for you in the respect that you are not worthy to receive this at moment, but hopefully, if it His will, His Holy Spirit will prepare your heart.
It sincerely absolutely completely does NOT matter if your priest is calling or if it is small talk. It matters if YOUR heart is ready to receive Him and if you are willing to DIE to your idea of what is what your life is about and receive and accept what HE wants for your life.
You may be very surprised - you may well never become a priest in the sense of what you assume this means. . .but something completely different . . .and something you may NEVER want to receive. This is dying to yourself and living to, for and in Him.
Lord have mercy.
