I'm going to a big family party this afternoon at my boyfriend's Aunt's house. My boyfriend has a few younger cousins (6, 7) and another who is around 12 I believe. Not to sound conceited, but they love me. I love them too. They're all such great kids and super sweet. Majority of the time at these parties they want to play outside (ride bikes in the road, jump on the trampoline) but they can't do it without supervision which totally makes sense. Since they love me, they always ask me to go outside to watch them. I've done it quite a few times now. Honestly, sometimes I just don't want to. I love these kids, but I really don't like being torn away from the family, especially mid conversation. It's been pretty brutally hot here as well which makes going outside even worse. They're the kind to keep asking every 5 minutes too. There's only so many times I can say "soon" or "after I finish whatever." They ask me because I'm the only one who will go. I know what it's like to want to play outside and need an adult but no one will go. It sucks. I remember being super sad whenever my older cousins wouldn't go out with me when I wanted to play so I feel for them. This isn't to say I'll never supervise them again, but for those times I don't feel like going, how do I politely reject them?
