My mother (im nc) pulls these stunts at anything where shes not the centre of the focus
When my brother and sister in law got engaged,my mother saw the ring (very small,but classy and tasteful) and said 'well its,um,very small'
They said they'd set a date
Cue a ton of whinging that they couldn't have THAT day as it was 'too upsetting!' so they said they'd set another date but that was 'too upsetting' as well
By the 5th/6th change of date that wasn't good enough,they went back to the original one
My mother tried to kick off at every stage of planning,from the dress to the food,it was done her way or not at all (she wasn't paying!) and was finally told to wind her neck in or not come at all,so she moaned and whinged to anyone who would listen about 'what a mistake the groom was making'
Fast forward to the wedding and as soon as the bride appeared,my mothers many (and fictional) illnesses flared up and played up all day (she tried to show up in a neck brace,which would have looked fetching against her black outfit)
Fake fainting,claiming her blood sugar was too hig/low,her blood pressure was too high/low,her heart was on the verge of giving up,she felt shaky,her arm was hurting/going numb and she kept holding her breath so she'd go red faced
We family members where so used to this so ignored her so she started sulking and tucked into the g&t's while making loud and nasty comments (loud enough to be heard outside) about the bride,other guests (including the brides family) and what she thought was crap about the day (all of it) to her sisters/our aunts (who hadn't been invited but she insisted they where found a seat)
She then puked up into a flower pot,lost her teeth and my poor father had to take her home in a taxi
Fast forward to their first pregnancy and instead of being pleased she was having another grandchild,she wailed loudly that she had to 'find the money for another christmas present' (shes loaded-money isnt an issue,but spending in anyone but herself is)
She then wailed loudly that she'd had 3 stillbirths (sadly,thats true) and that she hoped this pregnancy would 'go the course'
She banged on so much about her stillbirths that she convinced sis-in-law that every twinge was the start of one-she became really paranoid that she was going to lose her baby and almost lived at the doctors
It affected her so badly,they refused to have another baby even though they wanted two
Im glad to be away from the drama
