Yes yes yes- please stick it on the information sheet that comes with the invite!
So that all the relevant information is there- so I don't have to chase the couple up about it, working out what they want or what we should give.
I'm busy enough with work/life/small child
This, exactly.
The days are long gone when there was a virgin bride sitting around in her parents' home just waiting to field a host of calls from people wanting to know what they might like as a gift. Likewise, most people have too much to do already without having to play phone tag just to find out what someone might like as a gift.
As a pp said- weddings (like everything else) evolve, and thank god for that. No more being passed as property from one man to another, no having to wait until you're married to move in together and have (gasp) Sexual Relations.
We, as a nation, are more multi-cultural now as well- and many other cultures see giving money for a wedding as totally normal.
The giving of a gift, in my mind, is because you like the couple involved and want to help make their day a little bit more special. Admittedly, I've never been to any wedding where I feel the couple have judged what I've given- I probably wouldn't attend a wedding between people like that anyway tbh. Just do it with good grace or don't go.
