Adult children, female or male, are not pets and not there to fulfil some need for closeness in us.
No, they aren't pets, they are family. If you aren't close to your family, then I think that is sad, and I think you are missing out on something. Yes, I know all families are different, I'm aware there are very good reasons why some people put distance between themselves and their family, but I see that as a sad thing.
I often see girls the ages of my boys (adults) out shopping etc with their mums, I rarely see boys. Ds2 sometimes comes shopping with me and go for pizza, which I love. I know it's generalising but I think girls want to hang about with their mums more than boys do.
Maybe this is to do with the 'hobby' you have ? Personally, I prefer to go and watch a football match at the weekend, and I am just as likely to be accompanied by my ds as my dd (that said, my ds is FAR more likely to spend a couple of hours mooching round the shops than either of my dds).
And I dread the wedding and the first baby, I'll always be the MIL and I expect to come second.
Oddly, I've been to two weddings this month, (one where I knew the bride first and one where I knew the groom first) and that wasn't the case at either. Both sets of parents equally involved.
