MTH, I quote you:
'You don't know what they want the money for, perhaps they have huge debts and would like to start married life a bit more solvent.'
I do not assume that everyone is in debt at all; however, I do not wish to give cash as a wedding present, and I think it is rude to ask for it. As I stated earlier, the solvency or otherwise (which you raised, see above) of the people getting married is not my problem or concern, and whilst I am happy to give a present, I am not happy to donate cash for their debts.
'yes we all f* up in our own sweet ways from time to time, even you. So that's why a more gracious attitude would make you sound more reasonable than you do.'
As you don't know me, I resent your assumption that I have fucked up in any way at all. I also don't need to have a 'gracious' attitude. My attitude (and it chimes with that of others on here, so is perfectly reasonable) is that I agree with the op that it is rude to ask for money as a wedding present. I would happily, as others have said, pay for champagne etc, or club together with others to get a more expensive present; but to me just forking over cash is lazy and rude and shows a complete lack of effort and imagination on my part.
I don't come on MN to sound reasonable, I come on to express my opinion - you have it as above.
