i stay with my inlaws too. Hubby only child. Normally, i wld let my huuby does ALL the talking to his parents, i feel that it wld lesser the conflict. But general m one of those more blessed one cause my MIL n PIL are really super nice ppl. But due to different upbringing and ideals, there are still time that there are some conflicts.
For eg: i went to the last motherhood fair with her last year. m buying alot of diapers to keep stock cause it is very worth buying. she comments that dun buy so many, house gt no space to put, mind you, we are staying in a HDB executive flat, with only FIL, MIL, Hubby, myself and my no. 1. we have 4 rooms and 1 store room. Telling me no space to put?? super pissed me off, i go back n complaint non stop to hubby.
