This is me:
1. I time how long after they have logged on when I can talk to them [not straight away as i look desperate, but after about 5 or 6 seconds :P]
2. Send them texts and pretend I sent them to everyone. Like "Come online!" and when they do I'm like "ahh.. you were the only one to respond to that text :P"
3. Analyse the amount of X's at the end of each text/conversation
4. Sign on MSN at ridiculous times in the hope they MAY be online
5. Insult them ridiculously...
and more...
if i act like this to you I fancy you ;P
