We live overseas and, thanks to Covid, haven't been back to the UK to see family for 2 full years. We's got two boys aged 14 and 11, so they were 9 and 12 when this started. We met up with one set of grandparents this summer past, and it was hard work. The children, especially the oldest, have grown up so much. The oldest has a phone, his own group of friends and interests - he's moving into typical teenager-ness. My dad in particular found this really hard to deal with - constantly commenting about how DS's 'always' on his phone, not joining in with jigsaws or board games, not spending enough time with my mum (who adores them but frankly is much more accepting of them as they are - former teacher). We don't have any other children in the family - my sister is child free, no other siblings - my parents really aren't used to being around teenagers / phones etc.
We are due to go to the UK for 2 weeks soon (Covid allowing). I'm partly dreading it. The point is to spend time with family, but I'm struggling to come up with plans of what to do that can keep 80 yr olds and 14 yr olds together. We will be staying with them part of the time. It will be easier as I'm sure my dad will disappear to his garage / workshop most of the time. But with DHs family, we still need to come up with things to do with his dad (80) that don't involve being in a house together - his flat is really small and small talk / tea / biscuits don't really hold anyone's interest.
So what do your teens do with their grandparents on holiday? When spending extended time together?
