Probably am being unreasonable here but need to let off steam.
It's DC birthday and as usual mil and SIL have sent cards and presents using a shortening of DC name think Cece for cecelia or fifi for Felicity type thing. We use the full name. Always use the full name when talking about DC or writing a thank you or sending email etc.
just fed up and feel they are just doing it to annoy me now.
DH did on the day DC was born use the shortening apparently ( i.e. Said Little Fifi type thing) but that's it.
So how do I stop them ? Think I may start to shorten SIL children's names to make a point although a little childish. The thing is DC would not even respond to the name they use!
Go on tell me I'm being irrational DH has! X
