That's what i would have posted. cute girls smiling at me or saying hi, showing interest. But that's just one thing.

I mean a lot of things do. Certain people/friends do that if I haven't heard from them for a time. There's one particular one that does perk me up quite often. She doesn't message me all the time but when she does it always affects me positively Coffee or should I say espresso in particular, perks me up.

It all depends on the day!

Oh and payday. But then that's a generally perkier day
