I usually first check my e-shedule on my own smart phone. Actually I've been writing my schedule on my phone lately. It's really convenient and easy. I checked my schedule for this weekend before I make an appointment with my friend. If my schedule is clear in this weekend, I will call my friend to make an apppointment with him. I will ask him if his schedule is available this weekend. If he is clear this weekend, I will ask him to watch a movie together. However, if he is not free this weekend, I will ask him to just meet next weekend. Otherwise, I will ask him on what day he wants to meet me. I have to have patience to make an appointment with my friend. Actually, I am spposed to meet my best friend to see a musical tomorrow afternoon. Let me see if he remembers our appointment.
