I was part way through a LSR one day and was weaving a bit on one of my walk breaks. I was smacked in the back by a passing cyclist (he thwacked me with his hand. I'm glad I was wearing my camelback). I was on a thin path with wide grass verges by a wide road with very little traffic. I'm sure he said something to me, but being partially deaf means I didn't hear. Plus I'd been running for about 3-4 hours, so I wasn't quite with it. There was pleanty of space for him, there was no need to nearly run me over and smack me one.
Only issue I've ever had with a cyclist. Usually the ones round here are sensible and nice.
End of September I will be moving into a flat on my own. This is my choice. I probably could have found a house share for cheaper, but I really just want my own space at the moment (just got out of a four year relationship). The only housemate I want at the moment is my cat!
Usually depends on the actual size of the thing and what mood I'm in. I don't think I'd ever get a large in Starbucks for example, but might go for a large coffee in a cafe as it's not actually that big.
