We go to the same place on holiday every year for a fortnight where we have a house. My DB and his family usually come for one week. Unfortunately we invited PILs the first year we did this and now five years on they kind of expect it. I find them stifling and it spoils what is our only holiday though DCs and DH enjoy their company.
MIL is quite argumentative and difficult and has a very bad temper, she has yelled at DD1 on more than 1 occasion. DD1 is her step grandchild as DH is her stepdad. They both show SD quite a lot of favouritism even down to birthday cards, SD and DD1 have birthdays right next to each others, they send SD huge card with hand written poem, to Darling SD, etc etc, whilst DD1 gets small card. PIL I also find hard work, he often takes our baby DD and won't give her back when she cries, he is difficult to talk to and only really interested in himself IMO.
Anyway this year we told them there was not enough room in the house for them to stay as my sister is also coming so THEY'VE BOOKED A B & B!!!I feel so stifled.
