Yes,just say,sorry but im just putting our evening meal out,maybe nxt time,& close door.sounds harsh,but nxt time they might think twice? You must stipulate'evening meal' as 'supper' to some-depending on where they moved from,can mean other 'lesser' things-supper in north is just a quick bite before bed-especially for a child, its like a bag of crisps& a piece of fruit for example,so they might not think theyre keeping you from your hot meal? Also,it could be that they use that time for the dad to get the boisterous child out from under the mums feet while she does their evening meal,so dont encourage a habit of it,just keep on shutting door on them,theyl soon get the message unless theyre stupid! Maybe your hubby could attend their bbq's etc in summer alone,and just say "mrs aint as sprightly as i am" & theyl leave you in peace,i also suspect theyre keen to invite their neighbours,no matter what age,to drinks,meals& bbq's as thats the usual way for them not to complain about any noise or disruption caused by these things?!So youre right to nip it all in the bud,now.could be they cant guess how old you are,could be they think your only early 60's- so up to doing more than you are now? Just say,and tell them you have nearby family of your own,they may indeed think you 'need' them as youve no-one!
