DD’s godmother (my sister) only gave £15 for her 21st

[ScarletWitchM]

Not to sound massively ungrateful for any gift - but it was my DD’s 21st birthday yesterday and she is not at all spoilt so she was not as bothered as me… but her Aunt (my DSIS) & Godmother only gave her a cheap card and £15 as her gift.
Godmother (my DSIS) is not hard up at all & used to be really close to DD when she was little but she moved away a few years ago and has had less contact with us all since then.
It’s not that I don’t appreciate her gesture, but it feels really thoughtless and tight, but AIBU as it’s irked me?!

So it seem I am being unreasonable, so thank you for helping me see that.
DD had £10 from her for her 16th and 18th - and I wasn’t expecting anything grandiose but it seems I have been a bit cunty in my response having read the comments here

for context - we do make a big celebration of 16/ 18 and 21 in our family - but still I realise I have been ungrateful

What did you want? A few hundred?

You should be great full for whatever anyone gave!

🤣🤣 love this!

As are the first 8 of the final sentence.

How much money do you think she should have given her?
