Why is it - that when we burp, we are inclined to say - "Oops, pardon me" - or perhaps - "excuse me" - and yet if we happen to 'pass wind' (or, to put it bluntly - Fart) we laugh ?
Possibly because a burp is transitory and an apology means that it's 'over and done with'.
Whereas a fart makes its presence known for quite some time. It would be ridiculous to keep saying "Sorry, sorry, sorry,. . " for several minutes until the smell disappeared, so it's easier to try to laugh it off.
i think it depends who you are with.if i farted with people i didnt know well i would b embarrassed but when i am with my partner and i fart i laugh my socks off but still excuse myself.burps just happen but for some reason farts are hilarious.although if i do a huge burp which i am prone to when i am with my partner i laugh too.childish i admit but life cant be all serious :-D
