To be honest, the correlation between me having the Subway and my mood improving probably isn't as strong as it seemed the one time I really noticed it, but still, it is weird how little things like a bite to eat or just changing what you're doing can have a really notable effect on your mood.
Also, another thing I noticed when I went to get that Subway, it's quicker walking back from the local supermarket than it is walking to it - despite walking the exact same path both ways and it being uphill on the way back. How does that even work? It doesn't make any sense, and yet that's how it is.
Whenever I used to get really upset my mum would just waft her hand and tell me I must be hungry. It'd piss me off to no end, but she was usually right .w.;
