I like the spirit of this thread!
I have really lovely ILs as well, and I genuinely enjoy and look forward to spending time with them. MIL is just an amazing, strong, intelligent woman (I mean she did raise the man I love!) who I constantly learn from and thoroughly admire. FIL is loving and genuine and silly and fun, and he always makes a point to make me feel welcome. The extended family (MANY aunts and uncles, all very close) are brilliant as well, and everyone likes to let loose, have a drink, and laugh together into the wee hours on special occasions. I just love each and every one of them to bits. In fact, when DH and I were driving off for home after our last visit, I joked to him, oh wow, I think I may love your family even more than mine!
DH has pretty great ILs as well, if I do say so myself.
I like to tease that my DM and DF love him more than they love me... but that's only because they do! They really adore him. And my massive extended family all love and respect him. Just this week, an uncle, who is generally a bit guarded and occasionally appears stern, thanked DH for always taking such good care of me (something to that effect) and said he was glad they are family! That is staggering praise coming from him!
I really hope I don't sound like a twat just boasting about, because the fact that we come from very similar families - in size, closeness, proximity, personality, values - is undoubtedly a massive reason DH and I get on so well and have so much in common. When DH and I first began dating and I'd just met his entire clan, I was living far from home and family, and I joked to him that even if we didn't work out, I would keep "dating" his family as they reminded me of home and made me feel less homesick.
I know that I am extremely lucky and am eternally grateful that I don't have to endure the anxiety and suffering that probably most people deal with regarding ILs. Of course it's not perfect fun and praise and joy 100% of the time, but I am incredibly fortunate, and I do not take that for granted.
