FM is in their eighties, lives on their own so we see them every weekend usually for a meal. Tbh they can be hard work but mostly because of the generational difference, they are old fashioned, religious, daily mail reading we are none of these things but we love FM and try to be there for them. Our dc's are young teens so don't really want to spend much time with DH and I much less anyone older but they are also fond of FM so we've found that coming to us for a Sunday lunch or evening meal means we all get together and spend a bit of quality time together.
However everyone has noticed that FM fills their mouth with food before talking all through the meal and it really is horrible. My way of dealing with it it to not look at them while their talking because it's quite stomach churning, but it's not at all relaxing and it sort of affects the meal. I know that DH and the three DC's feel the same and its a real elephant in the room except one person can't see the elephant. We have tried saying sorry? When they speak to imply we didnt hear her, but you can't say that every time and FM hasn't picked up on it. If we are asked a question and have food in our mouths well do that hand gesture to say hold on let me finish chewing. We can't say 'spray that again' or anything jokey because FM would take offence. I'm absolutely sure they are unaware they're doing it and if you had a conversation about people doing it with them they'd join in and agree it's horrible. The problem is that meal times are so strained now that I'm sure FM must feel it and we don't want it to be this way, but what do we do?
