If I'm at home I'll be sleeping, eating, or on the PS3. And watching the Euro Under-21 Championships this Summer, of course.
Out of the house, let's see...
-Nights out - town, parties
-Concerts, gigs, festivals
-Gaming sesh's at people's houses
-Piss ups at people's houses
-Sitting off at people's houses
-Outdoor activites, e.g. paintballing (like on Saturday [with Marines, Rob : /]), Go Ape, etc.
