Because, it's the only place I can actually sit and drink a whole cup of coffee without "mum where's this" or having to holler at the psychotic spaniels!
Also because it's quiet and peaceful (til I get the strimmer out) and because it's helping desensitize me to buggie things (apart from daddy longlegs - that'll never happen, they're just wrong!).
And finally, cos if the blight/rain/slugs/snails/caterpillars don't get there first - it tastes bloody fab!!! ;D ;D ;D ;D ;D ;D
